Can't make my bf cum

Me and my boyfriend lost virginity with each other 5/6 months ago. Every time we have sex after a while he stops and he finishes himself off. We use condoms and he is says that because of them he doesn't feel much and that's why he can't cum with penetration. However, the same thing happens when I jerk him off or I give him head.

I talked to him about it and he said that it is not easy but that it's fine for him and that I shouldn't feel bad about it.

I really don't know what to do, this situation is hurting me, I feel useless.

Please send some help 💕
