My still cock and sex fantasy

I'm just a horny old man here on this site, I list myself as bisexual, don't know if that's right or not, I've got a really big urge to want to suck cock, not a whole lot to lie about at this age, already set in his ways that's only ever had sex with women in his life. Has a cock that's only around six inches, that sometimes gets pretty hard and sometimes not, can't cum anymore though, no prostate, But as I get older being here on this site watching all the different videos, I started to wonder what it would be like to suck on a cock. Over a little time, I bought some different sizes of realistic dildos to try, from small to large, I tried the small which was good, I could get all of it in my mouth, the middle one was good to I could get five to six inches in my mouth ok., the large one made my jaw stiffened up after just a little bit, I could only get about two to three inches in my mouth, and it was tight. I love to look at large cocks and fantasize about them, but in my reality the most I could do with a cock that size, is stroke it with my hands and suck on the head till it shoots its load of cum in my mouth. I love to look big cocks; I have a lot of them in my favorites. but this old man in reality would be comfortable with around six inches or smaller. I want to enjoy that cock in my mouth, where in can suck on it slowly or hard without feeling that I'm gaging on it. My fantasy or if it ever becomes a reality, of my attraction to a man is to just have pure unadulterated sex with him, no strings attached, no hugging, no kissing, no hand holding, just pure sucking and fucking, I have an attraction now to men's cocks, which I want to suck till they shoot there fucking warm load of cum in my mouth, there balls which Id also love to suck and fondle and I'd like to lick and suck there nipples which I'd like to suck till they tell me they can't take it anymore, and there ass, which Id lick and fuck you but I couldn't ever cum in you.. Then I'd like all of that done the same way to me. At the age I'm at now I'm starting to fantasize and imagine more about all the different sexual fantasies out there that I've never tried, I try to take things one day at a time, enjoy each day the best you can........
