Would a guy want a relationship with a girl they already had sex with?

Yes, they can! In fact, being intimate with her can even help make his feelings deeper and make him fall in love with her even quicker.

So, no worries there. ;-)

Any time you spend a considerable amount of time together, there is a natural attraction. How can you not like someone and still have sex with them? You usually will have something you like in each other or you wouldn't want to be near them, much less have sex with them. Sex is only a part of a healthy relationship. It is usually the easiest part too. It is maintaining the rest that is the hardest. And unless you have had over 10,000 sex sessions with this person, why would the thrill of the sex no longer be a mystery. I am pretty close to the 10K with my wife, but I still learn/explore/love new things almost every time we bump uglies.

Absolutely! But it does depend on the people involved and their views. I've known guys who have said they could never date a girl that would sleep with someone she weren't dating, so those are a no. But that's how it is with everything. Some are cool with it, some aren't.

My ex was actually a rebound guy for me. We started having sex almost everyday. After about a month he decided to tell me that he was not going to have sex with me anymore until we are officially dating because he didn't want meaningless sex. So I would say it's a DEFINITE yes! We were together for 3 years.
