Worried

Hi I’ve been seeing a girl for a few months now, we get on really well and I see a big future with her. We started talking about last sexual partners and she revealed what I thought was a high number, it was 7 and she’s only 21? It doesn’t changed how I feel about her but it bothers me subconsciously? Am I overthinking this and should it matter? I don’t want to lose her over my insecurities, am I being unreasonable?

Yeah, you are being unreasonable because it's none of your business how many sexual partners she had before she met you & likewise, it applies to her as well concerning your history. You need to focus on the present & learn to love & accept her as she is. The past is for learning from and it's sure not for living in.
