Interesting! I feel a little better and I guess he was just very open with me and comfortable and took it to another level. I never knew there was a DVD for prostate massage. Do you know where I could get that. I am a massage therapist so that could take my personal massages to another level :)
There are many straight men who like backdoor play just as there are women who enjoy it too. It doesn't mean anything: different things feel good to different people.
Now that you have split with your husband, you could ask him, since he has nothing to hide. But from my perspective, he is totally straight, unless more information becomes available. Many women do not realize that many straight men enjoy a lot of anal stimulation. However, I would personally draw the line at a penis-shaped strap-on. A gentle single finger anal massage is great foreplay when done by the partner or when done at the same time as a b*l*o*w*j*o*b. There is also a CD available that tells women how to give their man a prostate massage, if one needs a "medical necessity" excuse. My urologist mentioned that his nurse does a prostate massage in his office when advised. Some massage technicians include anal massage. For men or women, there is a lot of good feelings in the anal area, and one doesn't have to be gay to enjoy it.
