Is it wrong to be a single virgin?

My name is Sam, I come from Narre Warren in Melbourne. I'm turning 21 this year and i've never been in a relationship and i am still a virgin. Is that strange? I like to think that its because i'm a lesbian (yes i'm female) but i've just never had anyone interested in me 'that way'. Its not like i'm hideously ugly or extremely fat or anything. But i just feel like i'm a freak coz i'm still waiting for my first relationship at 21
