Recently me and my fiancé have been trying for our first baby. We have been together for 5 years and we have not had any luck . And I am 25

When I was a dumb bad teenager in my 16’s I was a dumb kid and was with a boy older then me well I wasn’t on birth control and we always had sex I was with him for 3 years and he always cummed in me and I never got pregnant keep in mind he was always a dirty person hardly took showers would do nothing but smoke rillos by there self and drink alcohol all the time and eat left over food he left in his room for a day or 2. He would always give me infections too when he would cum in me. I am wondering do you think he messed up my body to where I can’t have kids because he always came inside me and messed up my body ? Or it’s been years so my body should be fine ?
