Hi ladies

New here and looking for some advice

So my husband wants me to be on top over the years I have put on quite a bit of weight in fact we are both overweight but are both trying to do something about that so my husband wants me to be on top but he isn't fond of grinding I think because I am heavy it makes him loose his erection he prefers me to bounce on him which is great and fine by me the problem is I just can't do it for very long and feels like I end up concentrating on keeping myself going than actually getting to enjoy it but I also love that I get to be in control for the past few years it has always been him on top and doing all the work any advice when my legs start to hurt he holds me up and thrusts for a bit but I want full control he is also bigger than average so when I grind it goes quite deep and I am having some issues with bleeding at the moment (awaiting gyocologist refarel) please help a girl out
