what should i do...?

I am a plump lady. im thick. i have thick thighs, thick booty...

& my boyfriends got a short stump...

when we do have sex we basically do missionary.. once in a blue moon we'll do doggy but i think its kinda hard for him with my big ass... i tell him i want to loose it but he tells me not too, he thinks its sexy..... i just dont want him to get bored with our sex life...

Opinion's? Options?😭😂
