What are these red splotches and tear on my husband's penis?

Three questions!

1.) After sex my husband tends to have little red splotches right under and on the top of his penis. It usually goes away after he takes a quick bath and lets it rest but it’s making me uncomfortable. He says it’s not painful and it does go away shortly after and to lighten the situation we usually joke about the “pirana vagina” attacking him again. :~( Should we be too concerned?

2.) Another issue is a tiny little tear or cut that seems to open after sex right under the head…like a paper cut. It usually rips if we’re too rough or caught up in the moment.

3.) Last question! We’ve been together for almost 6 years and were never concerned about having children since he has 2 sons from a previous marriage. We decided it was best to let nature take it’s course and not to worry ourselves about “rushing” or actively trying to conceive. But it’s been 6 years already! After the first 3 years I decided to keep track on a calendar and when asking my OBGYN just before we were married she was judgemental and said “you shouldn’t worry about getting pregnant if you’re not married.”

Should I be worried? Is there anyway I can work on this fertility scare before consulting a Doctor again? Even though we’re married now I’m still a little wounded by the short comeback from my previous Dr.

Thanks! Sincerly Xaria
