I hope that almost a year later you found the right method for you, but here’s mine, just in case. I remember when I first started bottoming I didn’t even douche! Just made sure I didn’t have to go and a quick shower, never had an accident (oh to be young and healthy!) In my late 20s my eating habits worsened and I had my gallbladder removed, my bowel movements became completely inconsistent. I started douching and still after a lengthy session with a well endowed partner I had my first accident. It scarred me. I would douche for almost an hour sometimes. I finally got sick of that, especially when the act lasted 2 minutes. I finally have a fool proof system down. I, too, am on Pure pills, that, and a lot of water everyday, keep me pretty consistent. If I’m going to be with a big partner or I know they have amazing stamina, two hours before a session I pop two Imodiums and douche about an hour before. If not, then I just douche an hour before. I just use warm water and about 4-8oz (more than that will cause it to sit further up the rectum as mentioned a lot here) about 3-4 times. Then, I take a nice long shower, move around a lot, and at the end stick a soapy finger up there and squat to get any excess water out, rinse n’ repeat, and make sure it’s clear water! Never had an accident since. Fuck, the things we do for a couple of minutes of pleasure!
