I am naturally a lazy sex partner. I want to do more with my fiancé like riding And standing on my tippytoes and bounce up and down. But i get tired so easily, iI know my fiancé doesn’t care about it but sometimes i can tell he wants me to take control Nd get on top. What can I do to not make myself get so tired ? What other positions can girls do that besides riding? (Lol if their is any )
