If a guy has sex on the first date that doesn't mean he wants anything longterm...but it doesn't mean he won't either.
life is so random,but if you just keep in mind that sex doesn't equal dating you should be alright
If you're dating for sex, then have sex! If you are dating for companionship, just for with the flow, if it happens it happens.
Ask yourself this. "Is all I want from this guy a one night stand"? or "Am I ready for a long term relationship"?then figure it out.
YES, YES, YES. Sometimes the intention of the date is laid out. Sometimes they are so hot you just can't help yourself.Sometimes you just feel obligated to at least fool around.Seldom are you disgusted or grossed out that you must refuse.
