My SO still doesn’t know how to pleasure me after 10 years. His idea of foreplay is licking my nipples for 30 seconds before shoving his cock in me. Most of the time I’m not wet at all which is not comfortable. I’ve tried telling him what I like and don’t like but he listens for that one time and then forgets. He fingers me sometimes but mostly just jams his fingers up me and thinks that feels good for me. How can I help him figure out how to really pleasure me without offending him?
