Experienced switch, heart is a bottom. Like to be a straight sissy oral slave, chastity cage goes along with that. Have played with various people, am now between tops. Easier to find a female bottom, but they are not always interesting. Almost any women willing to be a top is very interesting. Forced chastity is always interesting. What i use seems to be often called a bird cage design, chrome or black Stainless Steel Male Chastity Device Belt Bird Cage Lock cock restraint Ring US that is one headline on ebay. Couple of different designs for the cage itself. rings are always 40 45 or 50 mm. With there was a 42 or 43 mm. the cherry keeper at shapeways, a 3d printer product seems interesting. don't know enough about it to know how to order, don't know anyone who has tested it. seems a bit expensive to plunge and not know the right size. i think 43 mm would be right ring, any size cage maybe would be ok. in the old bc3000 kind i have put plastic spikes (order from hobby type places) inside with crazy glue. they work great but the prob for me is that that design has a square edge on the rings. so the rings hurt when the scrotum enlarges at night regardless of size. i use the 40 and just deal with the issue by waking up, rotating, useing ice if necessary, eucarine to loosen, etc. takes some sacrifice after all huh. it's worth is to be "forced" to eat pussy every night and esp to suck ass for up to 2 hours + every night. while being insulted of course, then teased and put back or ruined or fucked to a clear cum orgasm (prostate) maybe once a week or month . "cum like a girl." "sissies dont have dicks" recommend the booty call 10 speed bottom vibe. not sure about auto sex machines. recommend auto spank machine if others are interested -- mistress leaves sissy alone, in corset and plug with spanking machine and goes shopping, comes back with someone she has met to show he bf is a sissy. hello to all, espec. any usa keyholders if any
