If the intent boils down to an existential choice between:
a long, skinny dick, or
a shorter, fat dick
I personally would choose the longer, skinny one... and I speak from experience, having been with a guy with a very thin, 9-inch+ cock; as well as a dude with a dick that looked like a crushed beer-can: about 4-5" in length, but much bigger around than I could accommodate!
But, I'm with the poster above: Give me a nice, average-dimensions cock any time! I want to feel him cum inside me, but I don't want my ass stretched, nor my intestines re-arranged to accommodate him!
I love it rough but not like that, you can slap and hit me all you want with your cock and smack my ass till its red but much more then that and I might knock you out. Love being pushed and tossed around into different positions and held down. And when its getting really hot you can get rough as fuck with my hole, slamming in and out, stretching it, fingers and more.
The biggest cock I have taken was on this Native American guy, he was 6’7” and about 230lbs. Which that alone was awesome because I’m 6’4” 175lbs and having a top that’s not only taller but that could overpower me was so fucking hot. He came in and within seconds he shoved my head down and pulled out the biggest cock ever. I tried to suck it but I couldn’t the head was so big, it wasn’t even close to fitting in my mouth. I’ve had several 10” cocks, a few 11” cocks, and even a couple of 12” cocks. He had to be at least 13 1/2 inches and it was quite a bit thicker then my wrist. I think he knew he wouldn’t be getting sucked and quickly flip me on my stomach, put a condom on, spit on my hole and slammed every bit of it deep in my ass. It hurt, it burned, and for the first time ever I thought I wouldn’t be able to take it. But I was not about to give up on getting fucked by this monster. He pounded my ass for about 15 minutes and there was so many time I didn’t think I could keep going. When he finally busted his nut I swear I was in the verge of death. He pulled out and within a minute I was walking him out the door, I could barely fucking walk and fell back on my bed just laying there for over an hour amazed at what just happened. A week later he came back, this time he spit on my hole and slammed in deep in me bareback. It still hurt but being raw it didn’t burn. And after a few minutes I was loving it and he slammed it harder and faster. He flipped me on my back, spread my legs wide and slammed it back in deep. After taking a hardcore pounding for almost a half hour, he shot a huge load deep in my sore hole. He quickly left. Turned out I knew his boyfriend, ran into them at the club a couple weeks after. Wished I could have fucked him more but they both moved. I would have been his fuckhole 24/7 for life lol
