To worry or to not?

My only form of birth control was the pullout method. But about a year ago my boyfriend and I decided to stop pulling out. Now we're not TTC and I know it's harder for some women to get pregnant, but when is it okay for me to worry? For reasons like what if we can't conceive? What if I have an issue with my reproductive system, etc.? The only thing I've noticed is that a lot of the time his stuff will come out of me. And I was wondering if anyone else experiences that. Tmi I know. Lol but it's just something I'd like to know about.
