Riding

Girls I need some tips on how to ride my man??🍆 I'm not that experienced with sex and he is... Also I have like 0 energy (have tons of health problems😌😞) and get tired super easy with the slightest exertion. My sex drive is super low. I enjoy having sex with him but it's like he has to put me in the mood I don't just "want" to have sex😕😥 Tonight he told me he wanted me to be on top but I was feeling ill so he didn't ask again. But I know he would love for me to be on top and I need tips/help to know how??! I want nothing more than to please him but I'm scared to try and then disappoint him😕 I'm not very confident when it comes to sex... Help a girl out!!
