Recently, someone reached out to me in private messages, sharing his experiences of an older couple bringing him to a doctor to be examined while they watch, and at other times, the woman bring her friends along, who functioned as "aunts'. Would I like to be in this situation, especially if women were mature? Oh hell yes !
Now I never really thought of this concept of being examined in front of others for a few reasons. One is the doctors for most of my physicals were men. As I'm not turned onto men, I usually don't develop erections during physicals. To have another male present would not do anything for me. To have a female nurse present may have the opposite of a turn on effect which is: If a male doctor is touching me & i don't get erect, having a professional woman (nurse) present while I'm not erect is not good for me, as I would always want to be erect in front of a female. So if i'm not, it takes away from any joy i could have.
Now. If a group of women, especially mature women, "organized" by setting me up to have an exam with a male doctor as they watched, & I understood clearly this was all about exhibitionism & voyeurism to them, at that point even if it were a male touching me, i'd totally get off on it. That said, I'm not into anything anal so unless there were a female audience to watch me get a needed real prostate exam, I'd probably draw the line.
Actually, I should hope to find a group of women who'd like to watch me get a prostate exam, because that would help me schedule an otherwise continually procrastinated medical / physical exam...
To sum up, i would say "Yes i would enjoy women, especially mature, watch me being touched & examined, though I would want it to be in a situation that would turn me on & be erect because being flaccid among women spectators is not a turn on for me" ..
