How long into a relationship is okay to have sex?

It's a personal preference. No one can answer this except for yourself or the people involved. You should take into consideration about the consequences. Also, assure yourself some extra time before making this commitment because doing something you aren't ready for is bound to cause regrets later into the relationship. If your ready for it, and you know in the back of your mind it's what you really want, then by all means go for it.

I won't be opinionated on morales but I think it would be best if you waited because sex should be something you share with a love one. So unless this person is someone you love and care for (possibly spend the rest of your life with), you should wait. Not because it's morally right, but because you don't want to take it too far with this guy now and later in life you break up and he brags about how he 'had' you. So at least make sure this guy truly respects you to prevent things like that. That's my opinion. Although it really only depends on when your absolutely ready. Good luck on whatever your decision.

I don't know I'd consider any time before 4 or 5 weeks too soon, because by that time, usually feelings have developed to the point that we want to be intimate.

But, your time has to be your own. If you want it on the first date, that's fine. If you want to wait 3 or 4 months, that's fine too. Don't let anyone judge you for being too early or too late. ;-)

I think if you are horny, first date sex is fine. I wish we could all just have sex with whom and when ever we liked. That being said, I am aware that that is only going to happen in some Utopian world. I suggest you wait until "you" want to have sex and are prepared to accept what ever consequences arise from it.

Depends on how I feel about the guy. If I know its going to be a long relationship then I usually wait until the time is right. If I think the guy is going to be just a friend. I don't sleep with them

I'd wait at least a month if not more, but that's just me.

The Answer to your question is when you know your ready to have sex that's your decision

I think that this is a question that you need to answer for yourself. I mean really it depends on when YOUR ready. Personally I think after a few months its okay to have sex but I know some people who'd prefer to wait a year or more, or even after marriage. If you talk it out with your guy than you'll probably have a better idea of what you two want. Good luck sweetie!
