So my current GF wants to try anal, but she has heard that regular anal sex(even once a month) significantly increases the chance of hemmeroids, rectal prolapse, and other complications that occur in that area of the body. Not necessarily right away, but later on in life. I've done some searches on here, and on google, but so far I've been unable to find any studies or statistics. I'm sure that regular anal sex isn't a sure-fire way to get your asshole to fall out, or there would be a lot of older gay guys wearing diapers... but I'm wondering do any of you guys know if there IS a risk? Or of any studies? I'm 6.5" in circumference... while that's not massive, it is big enough that I feel like it could do some kind of damage? I would appreciate any info, thanks!
