I cheated on my boyfriend multiple times, slept with ten different men, contracted STDs and I can't have children.
That behavior is quite rash, is there a reason you did these things?
Yes, I have always been kind of depressed about the fact that I couldn't have children.
I'm sorry you can't have children, but lashing out like this is only harmful to yourself and your boyfriend. Now he might catch a disease from you, and get emotionally wrecked because of your cheating. You need to see a counselor to get your feelings straight instead of ruining lives.
Ultimately I feel that people are too concerned about these sort of things.
People are concerned about these things because your behavior can truly harm others. You shouldn't cheat on your partner and you especially shouldn't put his health in jeopardy. I hope you can work through your issues as this erratic behavior can be dangerous to yourself and others.
