Could this mean that he lied about his virginity?

Well one night i decided to loose my virginity to a guy that i really like and thought he liked me too... anyway we did it in his car and he asked me if i was sure and i said yes... so the point is he's older than me (don't worry about the age) and i though he would know what to do but he asked me like two times if it was in, it really got me thinking if he was so experienced he would know if it was in or not, and after that night he didn't talk to me for a while and lost all interest in me and asked if we could only be fwb... so now im thinking if maybe he lost his virginity to me and now he wants to be flying solo in order to have with other girls, what do you think?
