I also tried using an aneros a while back, but it was really painful for me and I was unable to get past the pain at that time.

The thing is that I have prostatitis and I guess my prostate is very very sensitive. I kid you not when I say I almost passed out because of a prostate massage a doctor perfromed on me about a year back , and I have never passed out once in my life. I think one of the things that lead to my prostatitis was my extremely negative views on male ejaculation. There is evidence that mental tension can result in the physical "armoring" or tensing of muscles and other soft tissues in the body.

If you read some of wilhelm reich's work on the subject of orgasms, he says that the majority of men are very tense and this tension is disappated during orgasm.

also I once read an interesting article relating muscle tension to mental illness, that stated that the majority of mentally ill people had obsrvable muscle tensions of some type. I cant seem to find it so i will post it when I do.
