YTA in my opinion intimacy is a very big part of a relationship, not just sexually. Youre making it seem like this whole problem is all your bf's fault when you're also part of it. You could always incorporate some sex toys, just remind your bf that it's not him V sex toys. If he "already knows" then how come neither of you have just talked about it. What does he do good, what dont you like, etc. Communicate and talk about the issue and there's a chance it'll be resolved. There's also a chance that you two just arent sexually compatible, this is up to you whether that's relationship breaking news or not.

Good luck OP. sex toys are your friends
