TW: sexual abuse, scar tissue tears every time and is preventing me from having a normal sex life

I was abused when I was younger which caused a small buildup of scar tissue right at the bottom of my vaginal opening. I am an adult now and have a healthy relationship with sex but I tear a lot, almost every time I have sex. I get more than wet enough and warmed up and also use lube every single time but I still rip. It's not a huge area but it's enough to be really painful and prevent me from having sex for a few days until it heals again but then it feels like it gets more fragile every time. It's also quite triggering when it is ripped and sore and it's hard to have to deal with long term physical effects as well as the emotional damage and I'd like to be able to have a regular, fun, normal sex life.

Has anyone experienced this and have advice on how to strengthen the skin or reduce the chance of ripping? I believe it is similar to some childbirth scarring as well as scarring from tearing during penetration so I am hoping that if this is a fairly common issue then there is a solution. Any advice is really appreciated.
