Ive been with my girlfriend for 10 months and she keep telling me that Im bad at sex (which I think its true). She told me what she likes and dislike a thousand time and shes loosing patience. Im still confused, i dont know what to do. I seem to go too fast when she want it slower or too slow when she wants it faster. It always take a lot pf time to make her cum and she get bored often. And a lit of time she find it too technical and uninspired. shes very communicative but she does not want to always guide me and I understand her. But I struggle to read her, to react properly to her body response. I feel like an unexperimented child and its frustating. I put a lot of effort into it: read a lot, bought toys, experimented new stuff, etc. I really love her and I fear our relationship might come to an end if I dont become good quickly.
