I used to be a total top, but got persuaded to bottom once and haven't had to be asked twice since. I tell a lie. I met one Brazilian guy who was so big, he had to ask three times. The length I could have coped with easy, but he was really thick. I'd say about the same circumference as a Coke can. I'd had a few drinks and curiosity got the better of me, so I let him try. It took ages to get him in, and was a bit of a stretch, but worth it in the end even though I was a bit uncomfortable for the next two days. He wouldn't let me fuck him though - some macho bullshit about it not really being gay sex so long as he didn't take it. I love to fuck a guy and for him to fuck me, or, better yet, to be the meat in a sandwich.
