Penis

Hello I'm married have 3 kids, I'm 34 my husband is 44 and we don't have sex sometimes for months and I don't know what to do because I'm the one that always starts and of course all the experience in the world but my husband only wants BJ and to go down on me, I don't mind but the last time he was inside of his erection went down and after that I honestly don't even want to have sex with him and he doesn't say anything, when I tried to talk to see what I can help him with he told me I don't know how the penis work 💔😭🤦🏽‍♀️😤😩😳😂
