So, I've never told anyone this and idk how common it is

Somrthing I've been able to do for a long time now is I can make myself cum purely with thought. Like, actually orgasm.

I can visualize the feeling and my nerves react slightly similar to if they had the feeling. Sure it isn't as fun, but I used to do it before j lost my virginity.

Because of this I was able to know how it felt to be eaten out before I had ever even been eaten out. I knew the feelings the clit would get when stimulated, and I knew the feelings of tongue against skin. My brain was able to put the two together and create a feeling similar to it.

It doesn't feel near as good but I realized it could actually make me cum back when I masturbated a lot. Not just wet, actually cum.

Is this something other people know how to do or experience?
