Is it normal that everything turns me on?

I can turned on at the slightest thing now, and i feel like it's because i'm lonely.

It's true, i'm a decent way into life and have never had a 'relationship' with anyone. I've never kissed anyone, had sex or even gone on a date. Well, once, (gone on a date) but i don't count it.

First of all i feel like all that is totally pathetic, and in fact my friend has told me she thinks it is, too, and confronted me about not ever having had kissed anyone.

Anyway, today i realized how lonely i was when i had to lock myself in my room when my fantasies wouldn't stop. And i can't think about anything else lately. I would 'get a boyfriend' if i could, but no one likes me, so that would be a problem.

I just want to know, is this normal?
