Perineum Tear During Sex

Sex for me used to be AMAZING but since getting married, I don't enjoy it as much because 9 times out of 10, my perineum tears and it becomes a painful experience. I'm 24, no children, been married almost 3yrs, and while my husband is blessed down there, I'm confident it's not his size that's the issue. I've gotten to a point where I associate sex as something that's a temporary pleasure followed by pain that continues to linger and because of that, I can't get as aroused when the time comes or I'm just rarely in the mood to begin with. Before we could do it six times in one day whereas now he's lucky if I'm up for it two times within three weeks. It's stressful and I feel like less of a woman because I can't please him nearly as much as I want to. Has anyone else experienced something similar and found a solution?
