How fast can a girl tell if she wants to sleep with a guy or loves a guy?

This is a very interesting question.
From personal experience....
I think a girl can tell if she wants to sleep with a guy, after the first date. Although women know quite early on if they want to jump into bed with them, it often takes some time before she will actually sleep with him. Personally, I wouldn't sleep with a guy before I get an emotional response from him. Women need good conversation, honesty, and have to feel that romantic connection with a guy before jumping in the sac.

How long before a girl can tell if she loves you?? I think that depends on the relationship. I think from personal experience that love isn't at first sight, but I can definitely tell after a couple dates if the potential for love is there (in the future).

How much time does she need to read him??
Wow....i don't think guys are easy to read at all!! Thats something that takes some time. Although, women can always tell when something's wrong, or if a guy is lying to her. Women have this intuition about men...and they're usually right about something right away! I think that if you have a real connection with a girl, it's easy for you both to read each other. I feel we send of an energy to one another, and when you make that connection emotionally and physically, it makes understanding each other more easier.

I know instantly if I want to sleep with someone. But that has nothing to do with love. "love at first sight" I don't believe it. Usually it takes me months before I know if I love someone.

I think with me, I can usually tell on loving someone after I get to know the guys personality, their actions and what they like and if we get along. Typically within the first day of meeting, depending how long I have talked to him. How much I really am comfortable with him too. And usually if I have some idea that he has feelings back, or I get nervous with saying anything. Sleeping with him, I guess for me, if I get along with him as HIM in general, not to sound sluttish but when I know him more than the neighbor guy, I believe sleeping with him would come along soon. Reading him usually comes with how long you spend with her. Body language says a lot, but can be very confusing, so it also depends where things lead.

It is very superficial to think that way. That is lust not love.

No one (Man or woman) should sleep with another outside of marriage. Sure it is not easy to wait plus there is a lot of pressure sometimes. However, I can promise you it is much better to only have sex to your wife or husband. I am proud that I was a virgin when I got married.

It takes time to know if you love someone. You need to get to know them.

I am not sure that there has to be a difference between men and women here. Each individual has there own standards but if you are a person of good judgment, wouldn't you know right away? Within moments once you have spent some alone time together?

Not to say that if you don't have an instant connection things can't progress but generally I would have a good idea one way or the other right off the bat.
