my ritual for rimming...
a few days before, legs akimbo sat in front of a mirror (floor length is usually a good idea) i very carefully shave my arsehole, gooch, & balls.
on the day, avoid spicy foods, fried foods or anything that makes you gassy...i only drink coffee without milk (don't drink tea) etc...really be sure to wash your arsehole throughly with soap immediately before, get a finger in etc...
the ritual for anal play (if she's going to put a finger in)
same with regards to shaving and washing...
i also give myself an enema...some experienced girls will offer this...be sure to always use a clean nozzle.
if you're going to do it yourself at home, you can buy an enema kit from most sex shops (or search online for a home enema kit)
alternatively, from a camera shop, you can get a 'blowing tool' which will usually be used to clear dust from nooks/crannies on a camera/electronics...
it's essentially a ball with a nozzle (
External Link/Members Only) something along these lines...the nozzle is removable...fill with water, put the nozzle on, stick in and squeeze...then sit on the toilet and let loose...repeat till it runs clear
don't do anything you're not comfortable with
be very careful not to insert anything sharp up your bum...risk of cutting/infection/haemorrhoids!
all done, get your arse licked... and enjoy!
