Overcommunicated??

So my bf and I used to have an AMAZING sex life. I’m talking 2-3 times a day, everyday, for monthssss. And it was so good. But I slowly stopped giving him head bc I felt like he wasn’t really enjoying it. After a while we had a talk about what we really like or wanted more of. Now both of us feel like we aren’t good at sex. And don’t enjoy it as much.

I feel like my head just sucks, so I don’t like doing it at all now. And he feels like he’s not good at all so he’s not into it. We see each other 2-3 days a week and only have sex one time that entire weekend. And bc our sex life kinda sucks now, we keep trying to communicate about it to fix it- but that just makes it worse. Idk how to fix it. Help pleaseee
