Can your sexually active past (STDs) reduce your chances of being parents ?

WOW!!! You should be more careful with your personal life!!! STDs can definitely affect your chance of having kids, not to mention that STDs can be passed on to your child too. If treatable, you should treat it before having kids, if not better not to have kids at all. You can adopt but you need to be careful you do not pass it on to your kids by accident too.
