<human>: Can you succinctly summarize the text in 1-3 sentences?

I am currently 16 years old, and she is currently 17.

Two years ago, I had a relatively short-lived (about three months) relationship with a girl, and within a month, we were fooling around, and then had sex soon after. For me, the relationship wasn't about sex at first, but it pretty much degenerated into it, and we broke up.

When we broke up, I was rather immature and we didn't really keep talking. This year, however, it seems like she's going out of her way to get back on my good side. I don't really hold much resentment against her, but I'm really unsure whether I should try and get together with her. I'm feeling a bit dishearted as far as girls go, as I asked as many as four girls out last year, all rejecting me, with the last one being humiliating. Most of these girls I had lost interest in at one point, but I asked anyways. Because of this sexual frustration, I'm wondering if I shouldn't just try and get back with my ex, not to really date her, since I don't really feel like I'm able to date anyone, but just so I can have sex with her.
<bot>: I had a short sexual relationship with a girl, two years later, I'm sad about girls, want sex again.
