How can I make my boyfriend feel better about his dick?

My boyfriend has a great dick. It’s average sized, he knows how to use it, it’s the best sex I’ve ever had. I wouldn’t even want it bigger, as I’m pretty small down there and getting pounded in some positions can be painful. It’s also the perfect size for blowjobs.

He opened up to me early in our relationship about how he is insecure about it. It doesn’t help that like most men, he has watched porn since he was young and the dicks in porn are…insane. He even said that it was kind of difficult to watch himself fucking me because mentally, it looks small compared to porn and seeing his own dick is a turn off.

I’ve said everything under the sun to express how perfect his dick is, but he seems to think I’m kind of patronizing him or being nice (I am not…his dick is perfect to me). We both made a no porn agreement to put all our sexuality into each other at least for the time being and help shift both of our insecurities that had resulted from watching porn.

The other day, he told me that he is doing this thing called jelqing to increase his dick size and I asked why and he said for me! I thought he was feeling better about this but it seems like maybe he’s not.

Maybe there is truly nothing I can do, but might as well ask. Is there anything your girlfriend could do that would make you feel fully confident in your dick?
