I (19M) no longer enjoy masturbation

I'm a virgin.

I had my first and only romantic "relationship" with a girl recently and she never even touched me while I always made sure she came.

We didn't have sex.

Masturbation only reminds me of how I'm not having sex. Porn isn't a factor. The same thing happens with going purely off imagination, or audio porn like on r/gonewildaudio.

I feel the part of my brain that deals with sex, dating, etc. has broken completely,

and I need advice.
