What do I do on top?

Hi I've been with the same guy for 6 years we only been with each other and we dont watch po*n I have trouble when im on top and recentley my friend told me I was doing it wrong cause I set and lift up and down and my friend told me to roll my hips which...

still confused me because then I dont know how to roll them which ways and when im doing that do I still lift up and down or not at all I've never been so confused about something so bad, and she told me when your not setting straight up lay down on him and do it which made me 10 times more confused so anything at all will help me and is so very embarrassing so any specific information would help wonders and id appreciate it thanks a lot

my personal fav position: have him sit on a couch or chair or edge of the bed (if its not too high) and then you get on top of him with your back facing him (just like you are going to sit on his lap) have your legs close together and your hands rest on his thighs. in this position you can use both your arms or legs for leverage so if one gets tired you have the other. for some extra fun: have him pull your hair to your satisfaction. HAVE FUN!!

Just bounce up and down until you get a good rhythm, and then you can add fancy things.
