Help me out here, as a child of the 2000s who was raised in a strict Christian household, who has only had sexual contact with my ex wife, what do I need to know?

To be clear, I’m not ready to start dating or anything, I just get the feeling that most of what I was taught growing up is BS, or at least not nearly as big of a deal as I was led to believe.

So like, being nearly 33 and being where I am, I feel very much like a fish out of water. I have some degree of confidence in my abilities in the bedroom, but I’m riddled with anxiety about all of the other things, predominantly getting a partner pregnant(leaning towards not wanting to have kids, but want to let my brain settle to make sure that isn’t just a residual effect of not wanting to get trapped with the ex before getting snipped, and obviously know about condoms to prevent pregnancy) or getting an STD, as it was basically regarded as death sentence when I was growing up. Now, I’m under the impression that most STD/STI’s are fairly common, treatable, and mild. But I actually know nothing.
