Hey, you're not pregnant right? It's reasonable to conceive that sex would create a "connection" between partners in the event of pregnancy. In an age of contraceptives, however, that is less of a factor than at any other point in history. Old religious/social constructs that help protect individuals from un-supportable pregnancies are becoming superfluous, and society is changing as a result.
Should you feel hurt that this guy is unwilling to acknowledge you after you shared an intimate experience with him for the first time? Maybe. But should you feel hurt because you "wasted" your "virginity" experiencing it? No.
