^^whatever you do, even if you are shy, dont act like you are. TRUST ME, they are more scared than you are lmao. they're probably wondering "what the fuck does her pretty ass want with me? how the hell did i get so lucky? GOD PLEASE DONT LET ME CUM TOO QUICK!!!"
so relax and know that you're doing him a favor IF ANYTHING, and take control of him girl. ride his ass into the sunset!
personally for me, i lvoe being submissive and sometimes i love hopping on top. u dont have to always be on top. a fair equal opportunity position will always be doggystyle. takes effort on both you and him. push your ass back on his rod and look at him while you do it. well nevermind, he may lose control and bust a big one all over you way too early lmaoo, but you get the idea
