I've always wondered about getting that and trying it on myself. I am not interested in having sex from another guy, but I always thought it would be interesting to see how my dick feels. And, if I am ever to ask a girl to do anal with me, should I not know how it feels first?Or, you could try this.
Try bubble wrap and some lube,put it between the matress and box spring.You have not lived till you've fucked your bed!
