Geez mate. You sound like you are a hundred and twenty and in the twilight of your years! Get a grip - you're only 52 for pete's sake and still capable of an erection. That makes you a fairly young man, rather than a fairly old man - and well able to be a lot of fun.
anyway, back to the topic - daddy doms are fun especially if they can spank and cane a bit. Love it!
I am actually glad you have softed with age...Those young dominant men , and even older in their 30's and 40's are very diminant...and theres a better chance of finding a caring man in their older years. Thats my opinion, so I think now youre alot better then when you were younger. So you dont need to worry and feel lonely! If you like you can talk to me :P but I got to warn you I am far from a submissive :)
