Being disgusted about having sex with a prostitute or with a girl that's really into you, but was really into someone else before you and thus not a virgin, those are very different things.

Do they feel the same?

What if you aren't a virgin anymore. I am not dissimilar to you. If I ever have sex, I have no clue if I need to explain that I am a virgin. I probably would never tell her. But I can see how a male wouldn't be in his masculine while having sex when it is obvious he is much much less experienced. Of course different from the notion that a non-virgin woman is impure. But let's face it. We all, including female's, feel a bit of pressure from this concept. Yet is should not disgust you like it does.
