Missus finds out?
This would probably be a blessing in disguise, cos either she will turn a blind eye or we will be divorced - not a bad outcome.
Serious illness?
Possibly, esp if mobility is an issue
Lack of money?
No chance - other than food/shelter, sex is the next most basic need for me, so any little saving I have will get spent here.
No opportunity to escape civvie life?
I don't quite understand what this is. If it's what I think it is, then I will always create an opportunity to escape from my normal work/family life.
No erections?
My initial response was 'Yes, this would stop me', but then I remembered a guy I saw recently at a TPC party, who was probably around
60-65, low energy, and who didn't have an erection at any time at all, and he either got quick BJ's (still no erection) or just went around licking pussies. He didn't seem phased by other cocks drilling away around him, and in fact, he stayed till the very end. I kinda respected him for that.
More?
Possible if I caught a bad STD. That would create a damper on the whole thing.
