I'm not a frequent poster, but I've been around for a little over a year and I wanted to comment on the nipple stim. I also heard about it from over at the Aneros forum and like many guys, it did nothing for me at first. Gradually though, I started to get pleasant tingles which, over time, developed into orgasmic sensations. Whether these are the "nipple orgasms" that I've heard them described as, or simply incredibly good feelings I'm not sure and really don't care at this point.

Regarding hot spots, I have had some great success with pressure on the perineum. By pressing firmly with 2 or 3 fingers and moving the pressure point very slowly it created some of the most intense pleasurable sensations I've experienced to date. I was unable to prevent my pelvis from automatically thrusting (not that I tried very hard to resist). This area, like the nipples, didn't suddenly burst forth with orgasmic bliss. It's something you have to work at a bit but again, it's well worth it. I'm also reasonably certain that the area might have similar effects for women.
