This guy I know says he wants to have sex with me but he has a gf. he said that he doesn't care though. =S

Short and sweet seems to be a good theme for me today. Cheating is wrong. You know that. That's why you posted this question. You want us all to tell you that and confirm what you already know. You know what you should say.

I'd suggest staying away from this guy for a number of reasons. One, because he's dishonest to his own girlfriend, you already know you can't trust him. Although it doesn't sound like he had a relationship on his mind. Second, you never want to get physically involved with someone with such low moral standards (cheaters typically). There's two reasons for this. The first is they tend to have more anonymous "encounters" (if you don't know the people that well then you don't know their medical situation that well). The second is the people they're having these "encounters" with. If these "third parties" have low enough moral standards to have sex with someone that's already involved, then you can't have too much confidence in their sexually related medical problems, or lake of problems, you never know.

Moral of the story, find someone with morals. ;)

Don't, If they break up then its ok I guess.

...NO

? say no, duh. he's a douch bag.

Let's stick to the obvious. . .
1) All guys want to have sex with virtually every girl that will allow it.
2) If he has a girlfriend then why isn't he going there for sex?
3) Exactly why don't you see this as a problem?

Not suggesting that your apparent lack of morals is a problem but you might wish to read EVERY reply from both boys and other girls suggesting that the clear and obvious answer is NO and then picture yourself in his girlfriends shoes.

(Ignore Tahitisurfer22 as he falls under #1 above)

Good luck.

i would reccommend you say yes because he's really lucky if you do say yes and I would be hella excited if I asked that question and a girl said yes.

But YOU should care because this is about you as well as him, and do you have any clue how fast this talk will get around and turn you into trash? Gosh, just say, " Nooooo, sorry you're already taken and besides I'm not that hard up to just randomly have sex with every guy that asks" Then you ask back, "But don't you already have a girlfriend?" You need to learn say NO on the spot when you know you don't want to or can't without ever feeling guilty.

He's using you for sex. What do you mean you don't know what to say? Have some self confidence, some self esteem, and self worth.

Tell him "No. You are a pig!" It's that simple.

honestly I'm in the same situation you are. I don't know why guys are even with there gfs but we're like there f*** buddies basically. you need to let this guy know that if its more than just sex, tell him to ditch the bitch. but if you get caught, ain't your problem. he's the one with a chick, not you.. you're just living it up SINGLE BABY!

This guy is a JERK to both you and his girlfriend.

that is so wrong. put yourself in his girls situation. what if you had a boyfriend that wanted to have sex with another girl? wouldn't that make you mad? cheating is bad! bad! you both know that.

dont do it. it will turn out very bad and awkward.
and if his girlfriend finds out she will be really hurt..
you should never mess with someone already in a relationship.
if he really wants to have sex with you. tell him you can't unless he breaks up with your girlfriend.
but keep in mind you don't want a guy that just wants sex.
us girls need more than that in a relationship :P (if you even want a relationship)
but the way things are right now, say no.

rather walk away asap. you're on the verge of a big messy mistake.

Well, it's wrong that he has a girlfriend and he wants to sleep with you, imagine you are his girlfriend right now and some random chick is the subject of his interest, no, that would complicate things, make the girlfriend hate you, make him not take you seriously, but if you are the type who doesn't have regard for consequences, go ahead. I wouldn't, seriously would like tell him to go f*** himself and how could he do that to his gf? sorry, my own personal experiences lol. I hit my ex-bf after I found out he cheated on him and told him to f*** himself, so wrong, and he never even went out with the chick he slept with. (*sigh*) ^_^

use common sense

Tell him to go and die. and wish him he got the same thing next time that " I wish if you have a wife she will cheat on you too as what you do now you got ur karma!" and I think if you are clever enough you will not be used by that guy. he will just probably want to have sex and gone you will always be number 2 you want?

SAY NO
ive been in that situation before

how do you think his girlfriend would feel if she found out?

my friend cheated on his girlfriend with me
and I regret it so much now and I wish id never have done it

tell him he has to break up with her first
and that's only if you want to

if you don't want to just say no
as obvious as that is trust me don't do it while he has a girlfriend

i got so used and then he told everyone
and I got called "homewrecker" and all this bullshit

You should ask his girlfriend what to say.

I would say tell him no. Not because of morals, because he might be using you, because it's casual, etc.

Why then?

How would you feel if you were the girlfriend? Put yourself in her shoes. Then, your answer will be clear. I would be pissed, and I'm sure you would too. And I am a big fan of karma, because it DOES come back around, I promise.

DONT DO IT! trust me.ive been there.it is NOT a good experience.u will get hurt in the end, and feel like shit about yourself.that guy is a pig.what makes you think he is going to treat you any different than his girlfriend is you do have sex with him? just take everyones advice and don't do it! no matter what he says or does!

Unless you feel comfortable with getting used for sex and you shouldn't do it.

Whether or not he cares, you should.

1. Don't be a homewrecker, that's not cool.
2. Yes, it will screw with your rep.
3. He sounds like a douchebag, who would just screw you over as soon as he gets what he wants.
4. Not to mention all of the diseases there are out there.

Think about what you want, and what's right for YOU.

First of all, you do what you want to do. You are the only one who can decide what you should do. Second, if you want him for just sex, then have sex with him. Remember that you are contributing to the downfall of a relationship though. Apparently this is not a guy who would be good as a b/f. Whatever you decide, keep reminding yourself that this would only be sex because you could never have a relationship with him after this, but then again, would you really want to knowing he is a cheater? Personally, I wouldn't because what if you were his girlfriend and this was going on.how crappy would you feel? Just a thought.

It seems to me like he is just using you for sex. He has a girlfriend and I don't see him leaving her to make you his girlfriend especially if he could get sex outside of his relationship. He won't really see a point in making you his girl. He wants to have sex with you, but don't give him the satisfaction of using you.

if you respect yourself, you'll say no.

you say : no. and you do: not have sex with him.

Wow. Do you really like him that much? Once a dog, always a dog. You're getting in the middle of someone else's relationship, that's not okay. I wouldn't even kiss a guy if he had a girlfriend. I don't know, maybe you and I lead very different lives. If I were you, I would probably tell him no, and maybe let him know how disgusted I am to know he doesn't care about his girlfriend. What if she has an STD and he gives it to you, or what if he has one if he's so promiscuous. You may like the attention, but the guy who is attracted to you is not the right one. You should just move right along, find somebody else.
