I've only briefly looked at the topic list on MedFet, so if you want to direct me to a particular search to discuss this, or move to another thread, let me know. I have ~4-6 distinct kinks, depending on how you count them - rubber, sneakers, anal play and enemas, D/s, and mild/moderate bondage. I'm a real life physician, but not aroused by MedFet. If I had a woman partner who wanted me to examine her because she liked MedFet, I'd be happy to do it for her but still the kink itself doesn't work for me. I once was invited into a threesome by a professional couple in which the wife asked for an exam, enema and PIV sex while the husband watched. I enjoyed being with this couple for an evening and really enjoyed giving her the enema and subsequent PIV, but the exam part was somewhere between boring and mildly interesting.
So I'm really interested in what MedFet exams (play or in a real doc's office) make you feel like and exactly what arouses you about this kink. Now, this may be as difficult as it would be for me to explain why I get so intensely aroused by a rubber suit or an enema, but I'm still interested in how this works.
