well.... being on top is fun... lots of fun

being on top... allows you to set the pace... how fast.. how slow.. how deep..

so... it sounds like your boyfriend if he is asking has some ideas.. and could help you a bit until you get used to it..
but basically you are on top of him and you do the movement.. depending on the differences in height.. you can lay down on him and kiss him... and he can put his hands.. near your waist and help...

so is fun....
