I know this probaby isn't the best place to post this, but... I was diagnosed with pancreatic cancer and at most have 6 months to live. I have two friends, that have been friends since I was 14 and they were 13. They're both straight and married. But I've always wanted to blow them. We played around a bit in our teens and early 20s but no oral, no anal. What's the best way to approach them now?
