I've been frequenting adult book stores for over 25 years, and they and I have made some transformations over the years. Glory holes in an arcade are a little harder to find these days. In days gone by just about every bookstore arcade had glory holes until the law and bible thumpers felt they had to impose their beliefs on the rest of us. I did however find one in my area that still has a few.
I too have made some changes. 20+ years ago I was a young man in very good shape with what could be analyzed as a sex addiction. The only reason I went to the bookstores was to have some unknown person suck my cock through a hole in the wall as I watched the movie of my choice. I would imagine that the girl on the screen getting a huge load blasted on her face was the one blowing me as I actually came in some guy's mouth. Being as young and in shape as I was there was never a problem getting my rocks off in someone's mouth. Usually there was a game of jockeying for position among the cock suckers to see who could get the booth next to the one I picked. It was actually kind of fun. If the cock sucker I wanted to suck me off wasn't in position to get the booth next to me, I would leave after the first token ran out. Then the game started all over again as I walked around until I chose another booth
I never considered myself gay, or even Bi for that matter. I was always after some pussy, it's just that I needed to get off more than I was able to pick up some chick to get some. Plus it was a lot easier, cheaper and quicker to head to the bookstore for a blowjob and not have to do the dinner and drinks thing.
Lately I actually did get to the point of going down on a couple guys when the timing (usually me being quite intoxicated) and person were just right. I guess by this point I finally consider myself Bi and I even started to like to watch the cocks in movies instead of only watching the girl. I still never really thought of myself as a cock sucker because it was usually an isolated thing.
As I go the bookstores now though, there isn't as much action wanting to suck my cock and I find myself checking out who might have the kind of cock I'd like to suck. One night I was at the bookstore that I discovered that still has a few glory holes and the clientele that night was actually pretty nice. Not the usual derelicts and homeless bums in need of a shower.
