Me and my girlfriend have been dating for about 8 months now and our relationship is great. We get along perfectly but i have noticed that we only get intimate when drunk. When we are sober we are open about sex jokes and stuff but never do anything when sober. We do have sex pretty consistently but that means we drink pretty consistently too and sometimes it feels like we drink just to have sex bc if we are sober nothing will happen and i dont think its healthy. Something that bothers me aswell is most of the times we do have sex or we shower together or anything intimate happens the next day she will say like "after this part of the night i dont remember anything" and i tell her what happened and she wont remember having sex or showering together and that makes me extremely uncomfortable bc even if she doesn't see it like that it makes me feel like she doesn't really want it. I have asked her why we dont have sex when sober and she says its insecurities and past trauma and i get that and i dont wanna pressure her but she kinda shuts down the conversation and makes me feel like we will never get anywhere with this topic. How should i approach this situation?
TL;DR : me and my girlfriend only have sex when drunk. We are open about the topic but i dont feel like we are approaching it in a healthy way.
