Just a thought, but you might want to research "internal orgasms" for men (because, alas, that is the physiology you are dealing with at the moment). It was (and is) my favorite means of getting complete satisfaction.
No need to deal with "it", I could just take a hitachi magic wand (or anything that vibrates *strongly*) and press the vibrating bit firmly on my perineum where one day (money and health permitting) I will one day have the right part. Then it's just a matter of getting turned on and, um, "flexing" (I *think* it's doing Kegels).
No mess to deal with afterwards, and extremely satisfying on so many levels... and you can do it again and again with no letdown. Since it doesn't use the offending bits, it should work even during heavy HRT, but I'm not sure (I won't get to start that until my endo's first opening in January, alas).
Good luck!

Moderators: I tried to be as descriptive as possible without crossing any TOS lines... please let me know if I went too far and what I can do to fix it if I did... Still learning the ropes here.
