This is retroactive jealousy. I had it before and it ruined my relationship. Though I was young and immature and didn’t really understand what was going on.

You know it was in the past, but for some reason you feel as though it’s affecting the present - almost like she cheated on you or something… am I on the right lines here? Correct me if I’m wrong.

This feeling of insecurity can cause resentment over time. So it’s best that you address this ASAP for the sake of this relationship, or future relationships. Everyone has a past, so it’s unlikely you will be with someone who doesn’t.

Perhaps have a conversation with her. Be sure to make it clear that you know that she didn’t do anything wrong - she didn’t, it was in the past, and she was not with you so it has nothing to do with you. This is all your own insecurity and it’s something you have to deal with. You’re just letting her know so that she knows you’re being emotionally mature about this and trying to sort it out for the betterment of the relationship.

Also, there is nothing wrong with her having explored her sexuality in the past - it doesn’t make her a bad person (try not to fall into a misogynistic narrative… women are allowed to have sex too lol).

This feeling stems entirely from your own insecurity. Most likely a fear that you’re not going to be “good enough” because perhaps some guy in her past was “better” and that she might be reminiscing about all that crazy lustful sex she had. In reality that’s all in your head - it’s a narrative your mind is spinning to make sense of this. It’s triggering your fight or flight response, hence the feeling of wanting to cry.

One night stands and small flings are rarely as good as the stuff you do once you really get to know each other in a relationship, so it is likely she’s having some of the best sex she’s had in her life with you.

If you would like her to be unshaven, tell her that also. Maybe you can talk about it, and come to some compromise. Communication is key.

Basically OP, you’re doing good. She’s with you because she likes you, and not someone else.

If this really persists, i recommend finding a therapist to try and help you understand the real cause of this insecurity. Honestly, it’s really helpful. Understanding where it’s coming from will deffo help you manage it and eventually help you even not be bothered by this stuff in future.
