Do you feel like it could be based in some emotional issues? Ie. you feel undeserving of pleasure?

I would think giving would be equally unattractive if you were asexual. Def wouldn’t call you dysfunctional.

Personally I am all about my partner as well. For me it’s rooted in desire for perfection, etc. knowing they were satisfied is worth so much more than an orgasm for me.

When it comes to recieving, my head is never in it.

I know many individuals who are just givers, that is the thing that provides them pleasure. Regardless of the reason, there is nothing wrong with being that way.

Not sure if this helps, but communication always helps and the right partner. Sometimes it just takes that one person to bring you out of your shell.
