For me it was simple; I like the sensation of a cock stiffening up in my mouth. Then the first guy who came in my mouth was a heavy smoker— the taste was so bad—- thought I was going to die. Continued sucking cock and eating cum —many different flavors— like beer.
then I got my ass eaten and fucked by a condom’nazi’. I was his bottom for years and he loved to watch me get fucked by other guys ( always with condoms ). Then he and one of his buddies decided to stealth fuck me & creampie me. At first I was concerned but found it was so much better bareback that was all I would do. Then became literally addicted to being fucked. I needed it at least twice a week or I would become terribly depressed. Eventually became POZ then on meds. Will still suck and fuck anyone anywhere.
