I'm 25 years old boy , but i'm still virgin! What problems may occur to me?

1- what do you think, "you are a boy" no you don't. You was a boy than be teenage and now you are a man.

other thing is you are a man like virgin. virgin means "a person who has no experience of a particular activity" but your question shows you have a lot of information about virginity and sex. so in my views may be physically you could be. but according to knowledge you are not.

Your main question is that related any problem to you.

the Answer is "You'll not face any problem without any wrong sexual relationship. No disease discover according to your question in my knowledge.

You're 25 years old, you're not a boy

You may end up considering rape

just dont be an stipid and dont make it public
