I think you pretty much answered your own question!!

Another thing to add though is that a straight guy offers a completely no-strings-attached dick to have fun with.

I started by sucking my own cock and even showed off. All the other boys in the neighborhood were not circumcised. As we compared boners one girl said she didn't like the way their foreskin looked and would only suck my cock. One boy also liked my cut cock and wanted a turn sucking my cock. I had never had the desire to suck another boy's cock but didn't mind if a boy wanted to suck me off. I agreed with the girls about only liking and sucking my own cut cock. I didn't know what gay/lesbian was as we looked at porn magazines we found in the woods or boys brought from their Dad's or older Brother's porn stash. One boy brought guys with guys and some were cut and others not but I liked to see guys sucking other guys boners. We would all jerk off looking at the porn and one guy sucked us all off. We also saw ass fucking and we all tried it. There was just something about butt fucking I really liked. Years later I found out the guy we used get BJs from and ass fucked came out as gay. I would tell the sex story and always got my cock sucked. Over the years and after I got married I stopped sucking my own cock. I always enjoy seeing a nice cut cock or if he isn't cut as long as his foreskin was fully pulled back. But then just to look. So I don't find it funny that gay guys want to suck my cut cock and take it in their well fucked man cunts.

I love the feel of a cock in my mouth, as much as getting sucked. Try it, you just might like it!
