What’s the deal

So I used to always do backdoor play with my ex b4 I got pregnant even after having my child he was must larger then my now husband in length and girth he was BIG

My now husband is much smaller in both areas but no matter what we do backdoor time just won’t work

I thought maybe it was how tall he is we have tried everything and I’m getting to much pain

I feel disappointed cuz I want it so badly but my body won’t let it happen

And yes, before anyone says we use  number lube forplay ect ect
