We all need to stop asking about what’s normal and what’s not when it comes to sex. You like giving, you like being in a position of control, that’s the most arousing and sexually gratifying place for you. If you are receiving sexual pleasure from what you describe as “giving” then keep working it!
You don’t have to be on your back in order to receive sexual pleasure, remember that.
If you’re getting off on it, if you’re having orgasms, if you’re truly satisfied with your sex life (and your partner is satisfied), then what on earth could be wrong with that?
