I think it is that we get over a lot of our hangups and want to have experiences before we die. I still love to fuck women but it is easier (not easy just easier) to find guys at my age which also has a lot to to do with it. I may be 73 but I think I am hornier now then when I was young!Is it a hormonal thing?
Or, what?
Never had a m2m experience, but in my old age I have an increasing urge to suck cock and swallow cum.
Thus far, I'm just at the "curious" stage; given the right circumstances, I'm sure I would suckcumbto my urges!
