There are certain factors to consider:

The decision has to be mutual.

If either side is feeling the least bit of discomfort, then it is probably best to put it off; after all, what is the big rush?

On the other hand, disregarding the more popular decision to not have sex on the first date, if both parties are very attracted to each other and see no qualms with the sex on the first date, they should go ahead with it.

Ultimately, it is up to both parties to decide whether they want to have sex on the first date or not.

Whatever comes of it, all depends on them.

Actually, for gay men (of which I am one) it all depends. No one is going to consider the guy a slut for doing it; on the other hand, there is a wonderful stream of thought on the younger guys that it shouldn't happen.

Good for them. AIDS is a very big consideration, and you'd better know what you're getting into before hand. (HIV/AIDS volunteer speaking). Think. THINK. A lifetime on debilitating drugs that give you horrible side effects isn't worth a few minutes with ANYONE - no matter how cute and adorable he is!

So - no, won't judge anyone that wants to do it, but please don't do anything stupid you'll regret later. Use a condom, do some common sense stuff too delicate to commit to writing on a non-gay web forum, and for heaven's sake be careful.

End of sermon. You may all rise. :)

If your old (with one foot in the grave) and you don't know where your next piece of ass is coming from, do it. You might die waiting for the right time ;)

How else will I know if I like her?

Personally, no. Unless maybe you had been friends for a long time before then.

I would say don't do it unless you're mature enough to put up with the consequences of a lust at first sight encounter. If one does have sex on the first date there are expectations from one side or the other...unless you discussed a "booty call" before the clothes hit the floor. My thought is to get to know each other a bit first. You don't have to be on hold forever but why not be sure that the person is genuinely interested in YOU before giving it all up in a nanosecond? In today's sexual climate I think it would also be wise to find out who your parter is and where they've been! You're only as sexually healthy as your last partner...at best. If you feel the need and are that sexually starved or attracted beyond belief then, at the very least, use protection. I would still err on the side of caution though!

No. Sex should wait at least until engagement, marriage is even better. First date? Hell no.
