I'm a single guy looking to rack up a few more fond memories before the parts start to go and I'm clapped out.  

I'm totally discrete and respectful of any boundaries or conditions you care to set.  I don't even need to be part of the action if you are just looking for someone to watch or help out in some other way.

I'm open minded and nonjudgmental so feel free to make suggestions but I am probably not going to be into the more extreme activities particularly causing or receiving pain
