Girls...I need your help!

So im overweight (195) and my boyfriend has a smaller penis... like not suuuuper small but small.

I want to have a great sex life because our relationship is amazing in all of the other areas.

In the sexual department it’s not like super bad, but it’s not great mindblowing.

We can’t try alot of positions because me being on the fatter side and him being on the smaller size... its not great, where either he cant reach or i cant super ride him...

so far missionary with a pillow under me works, but i want other positions or ideas, he can last for a loooooong time so missionary for a long time get boring... plus, i feel like a starfish ( haha even if a try to move and touch him and do stuff)

We kinda tried doggy and it was a no go...

we even tried anal wich was good 👌🏻 but it’s not something you can do everytime in the spur of the moment...

please girls... any ideas, tips... ?
