When I am orgasming through sex with a partner I experience my orgasms as colours. Sometimes they are purple, yellow or red. The colour isn't solid but kind of moving/wavy, sometimes in the form of flower petals?
I had no idea it was weird until I told my partner after that my orgasm was a purple one...then consulted a friend and she had no idea what I meant.
I'm guessing it might be a form of synesthesia? But I don't have it for anything else..
I guess my question is, am I alone? Does anyone else know what I'm talking about?
