Sex, vaginal tightness, birth scars

Body: 

I am currently seeing a PT, besides prolapse my biggest concern is being able to have sex with my partner. I had 2nd degree tearing and of course stiches. So my vaginal muscles are so tight my partner first almost cant get in and if he does he cant move. Besides the muscle tightess i have a scar from stiches in the muscle on one side that is really the part that keeps us from doing anything, I can feel it and it feels likes its stretching uncomfortably and is tight enough to retare. PT is supposed to help and she gave me some things to do to help me relax when that moment comes which boils down to foreplay. I feel like the PT will help some but its been over a year and that alone makes sex hard. Anyone have strategies for this?
