I’m at this point in my relationship with my boyfriend where I’m really confused. It just seems like sexual activities that were fun or used to work just don’t work anymore

Like i used to make him cum just from giving him head and now that doesn’t happen anymore , then when we advanced to having sex he used to have to pull out and now we have to go through different methods to get him to cum and it just takes foreverrrrrrr.

A few days ago we were horny , he fingered me and gave me head and that made him hard as a rock , by the time he tried to put it in it was semi hard but it just went down hill from there . He went soft so we went back to giving me head , i guess because he could’ve either been embarrassed or didn’t want me to lose interest . So i tried to be extra aggressive and dominant hoping that would turn him on again but that didn’t work either , so i tried to start jerking him off to get him hard myself and that didn’t even work he did it himself and he eventually got hard , i gave him head and then he tried to put it in me again and yet again the same thing happened..he went semi hard so he held half of his 🍆 and put it in a little but it didn’t work , gave me head again and he told me to play with myself , i had a few orgasms and he eventually had one. That whole process took like an hour , idk if he was in his head too much but i can’t help but think that i was the problem , like an i still attractive ? Did i do something wrong ? Maybe it’s not exciting for him anymore ? It’s never been that bad before and it turns me off to the idea of having sex with him anytime soon . Idk if this has happened to anyone else before with their SO. But it just made me feel insecure and I’ve been thinking about it since Tuesday 🤦🏽‍♀️🤦🏽‍♀️
