I am a 50+ year old married man who is curious about performing fellatio. I am thinking about meeting a guy I met on a cruising site at an adult bookstore so that I can perform fellatio on him. What are the health risks and how can I minimize them? Is it safer if I don't swallow? What if he ejaculates in my mouth, but I spit it out? I could have him pull out before he ejaculates, but I'd still probably swallow some semen - how risk is that?
