<human>: Been together nearly 1.5 years and we're best friends. We both get quite jealous though. I know this is common but I have great anxiety with anyone from her past. She said she was never looking for sex but for a relationship but guys would always just want action (didn't have many guy friends either unfortunately). 

Basically, she's hooked up with way more people than I have, and although I don't necessarily want to do that anymore, it bothers me. But psychologically it's because growing up I always felt unattractive, the ugly one and I'd be best friends with girls where they'd obsess over other hot guys. It was always the cool people hooking up.  I never felt that and hookups never just "happened" despite me being social. Everyone else would have things with people or hookups.  I was never an option to girls it felt, though some had crushes on me. As I got older people found me more attractive and girls were more into me, however still nothing really happened. I had a relationship and 3 drunken makeouts. 

I understand that no number of girls can make me feel better about her past even if I had hooked up with 10. I need to somehow find a way to face it and not feel curious or competitive if an ex of hers was better or hotter etc.

Can you summarize the given text in a few sentences?
<bot>: Girlfriend had many more hookups than I did, I don't know how to deal with it. I know I'm the biggest and treat her well, but there's this psychological problem with "hookups" I have.
