Ladies, if you got in bed with a man, and he said he was a virgin, would it be a massive turn off, or would you not mind?

There is no reason why anyone should care. What do I think of a person who has never flown a plane? What about a person who has flown a plane? Has or has not ridden in a roller coaster? Eaten ice cream?

"Virginity" isn't a real thing. It's a social construct that is defined by a lack of sexual experience. Someone's sexual experience, or lack of it, is irrelevant to anyone but themselves and their sexual partners. Anyone who actually cares about someone else's sexual experience or lack of it has a real problem.

It will be a huge turnoff. I wont go to bed with him.

I honestly think it wouldn't matter to most women.  Male and female virgins think they're less attractive to potential partners but they're not.  Any good partner will help them to feel comfortable and will teach them how to be fun lovers.
