Sex Therapy

I think I need sex therapy. Or regular therapy. Or both. I only had sec with one other guy before my husband and I’m regretting it. My husband has grown more and more terrible in bed. The guy I lost my virginity to, rocked my world. So it sett expectations extremely high and at first my husband was decent but as time goes he just isn’t doing anything right.. but I don’t know how to communicate that because I still need to explore my own body and figure out what I like so I can tell him… but it’s hard because the guy I lost it to, didn’t need any instructions or direction. He just DELIVERED😩🙌🏽. My husband is sweet and kind and honestly an amazing man but the sec SUCKS and I cannot go the rest of my life like this. I have a ridiculously strong attraction to big muscular men and have dreams/fantasies often about having sex with buff men I have seen. My husband use to be super buff but now he’s a little smaller. Which is fine!! I think. Idk I feel like I didn’t explore like I should have before getting married abd it’s horrible but I wish I had more experience’ We both need direction so bad, where do we start?
