I think you are going to get many people on here saying no, but my answer would be ABSOLUTELY. It depends on the people.
I know there are some guys who have this weird hang up that they can't get into a relationship with a woman if they have sex right away. I think that's high B.S. because it's like he's saying he can't respect a woman for doing something that he feels perfectly fine doing himself. However, NOT ALL GUYS are like that -- and if you are talking about one who doesn't have that hang up, I would say of course it's possible.
Now, my question would be -- for how long has the hooking up been going on? My thoughts here are that it would be easier to make the transition from hookup to relationship if the hooking up hasn't been going on for a very long time. If there is a long pattern of hooking up, then I think it would be more difficult.
I'm not sure how most people get into relationships. For me, it usually involves lots of alcohol and long crazy road trips, but I'm sure there are other ways.
