guy who wouldn't let me touch his balls. How common is that?

I'm not judging you at all, I was only just saying "do it with consent" and it does not mean that I think you're not. I'm glad you respected him and didn't insist! I was also saying people shouldn't be surprised because some people don't like something mainly because people are different regardless of gender. And I get it, it was unexpected and surprising, but the important thing now is that you learned from it! And your apology you said to me in your response to my comment, I forgive you!
