He rips me

Ana
My boyfriend has a girth and I have like the smallest vagina in the world since I'm very petite. When we first started having sex it was painful & I needed a lot of lubrication, otherwise it would have been impossible. Many months later we have learned and worked ways to make it less painful for me but occasionally he still rips the bottom of the inner labia & I wonder if I'm ever going to stretch out to where I won't rip anymore. I try to have sex every other day or rest two days in between so that I can recover but also so that I can stretch out for him but so far I always rip and have to wait at least one day or two to get well.
