I’ve been with my gf for 1.5 years and it’s wonderful, we literally complete each other. But I notice that her bj is not that great, it’s “hit or miss” tbh and initially kinda painful since she is not that experienced. I tried to address this problem once or twice (we talked openly about sex life since it plays an important part in our relationship), but it still seems off. Recently I found out that she’s into BDSM, starting with me biting her pussy, spanking etc and her biting my dick. Sometimes, it hurts and kinda lower my mood. Few days ago I found out that my dick head (idk the terminology) has new skin grew which mean it’s damaged. How do I convey to her? PS: I’m not influence in giving bj ofc so it’s hard for me to “teach” her
