Thanks for the replies, everyone. I'm glad to hear that there are at least a few people who have been okay with leaving it out at times.
There are parts of the exam that I'm definitely into -- I would love to find a play partner to do really thorough heart and abdominal exams. There are other parts that I don't really care about either way, like HEENT or blood pressure, that I'd be totally up for doing or receiving very thoroughly if that was was my play partner wanted. But the "intimate" exams...I just don't think I could do it. Giving or receiving. I don't think it's just personal anxiety or body image issues: I'm not even interested in looking at pictures or watching videos of genital exams (realistic or sexed-up). They do worse than nothing for me -- they are a complete turn-off. For me, the best (most arousing) thing is just a good teaching video of heart or abdominal exam techniques with a patient I think is physically interesting.
This is kind of private but we're on an anonymous forum so what the hell: I'm not really a sexual person. I think I experience this "fetish" differently from most people here. It's more of a fascination that is also somewhat sexually charged. By sexually charged I mean it's arousing, but not in a way that I would want to act on it with another person -- not with sex, and not with other forms of mutual stimulation. I honestly don't know what would be the ideal end point of a play exam for me, but I crave the physical contact of an in-person play exam with extended heart auscultation and abdominal palpation. With a real romantic partner (as opposed to a play exam partner), I could imagine that morphing into sensuous massage, caressing, kissing, things like that, but that's as far as it would go. I know that all those things are only the appetizer for most people here. Even if I were to manage to work myself up to giving a genital exam, I don't even really understand what the other person would want me to do. Like, I know in theory, but I have no idea what it's like to want something similar. It's just so completely not part of my experience that I can't imagine how I could ever manage to make it pleasurable for an exam partner. (Obviously, I realize that finding a real romantic partner who also doesn't want to be sexual would be difficult as well -- but such people do exist.)
So, I know that an exam within my (current?) boundaries would be totally unfulfilling for most people, and I completely understand that. I certainly wouldn't want to set someone up to be disappointed, or set myself up for something that would be so uncomfortable I wouldn't be able to go through with it. Like I said above, I don't even know what my ideal end point for an exam would be. For some people here it's sex, and that's cool. For others it's one person bringing the other to orgasm, and that's cool too. But for me it's neither of those. I guess ultimately I'm wondering if there is anyone out there who is as vanilla as I am, while still having this weird medical semi-fetish. Or at least who wouldn't see an intimate but relatively non-sexual (or non-sexualized) encounter as a waste of time
Please don't turn this into a debate about the technical definition of a fetish or of asexuality -- that dead horse has been beaten in another thread.
