<human>: I've been with my girlfriend for a year now, and things are pretty good. She's my first girlfriend, so I lost my virginity with her.  She's had three previous relationships - with a mixture of males and females. I know it's completely irrational, but just knowing that she's had sex with three other people really bothers me, and makes me feel weird whenever I think about it.

I know it's unrealistic to expect someone to have had no sexual experiences once they're past the age of, say, 18, and I know I'm a somewhat special case for not having any experiences before her, but I can't help but feel bothered by this. My mind goes crazy wondering exactly what she's done with each of them, what's unique to just us, and, inevitably, how I compare to them.

I don't have one specific question, per se, I was just wondering whether anyone else has experienced these kinds of feelings, and whether anyone has any tips for dealing with my insecurities (and I do know that they're *my* insecurities, and that I can't get annoyed at her for having a past or anything like that).

Thanks in advance!

Give me the gist of the text in a nutshell
<bot>: Knowing that my girlfriend has had sex with other people makes me feel uncomfortable. Can anyone sympathise and/or advise me on how to deal with this?
