I've got a 6 gauge PA that I first got sometime last year. Started out at 14 and worked my way up from there. As far as fucking goes, I don't have a problem using mine. If anything, I like keeping it in when I top. Every bottom I've fucked with my PA so far has said that it hurts a bit at first when taking it, but it feels incredible later on. Though most of them do get a bit roughed up inside and end up bleeding a bit. Also, I didn't have to wait that long for mine to heal. Fuck, I was jacking off the day after I got mine, and back up and fucking again within about a 1 1/2 to 2 weeks. And as far as how it feels, sometimes it feels a bit uncomfortable when I sit down without boxers on. And even when I do have them on it still feels a bit uncomfortable against my balls. But the rest of the time I love having it in. I especially love hanging locks and other objects off of it.
