Help 😕

Tori • Love LIFE ❤️
So I'm Bisexual. I have a girlfriend and we're serious. I mean we live together and all. She ALWAYS Pleases me but I've never really done anything with a girl but kiss. I feel like so wrong because I don't know what I'm doing so when she's done going down on me I just thank her and go to sleep. I want to please her too but I don't know how or what to do !! ANY SUGGESTIONS ?!?!?!
