Self pleasure combined

Does anyone combine masturbation as part of other medical fetishes? For example during exam play my partner enjoys touching herself and and right before she orgasms she tells me and positions herself to receive a butt injection right at the moment of orgasm. She says the mix of anticipation/pain/pleasure release is incredibly arousing

Mostly I masturbate while auscultating my heart or vice versa and the one benefits the other. I'm (still) dreaming that this will happen once I meet a similar cardiophile woman to live our fetish extensively with.

Masturbating while stimulating the anus/prostate/perenium either with a massager or toy can give an explosive and pleasurable climax!

I masturbate while taking a mild soapy enema of 2 litres using a long colon tube. The fetish for enemas started as a young boy of 6, the combination of masturbation and enemas at 13 when I experienced my first orgasm while taking an enema. I still use the combination of masturbation and enema for the release of sexual tension when no female partner is available for sexual intercourse.

I had a male patient, whom I would have masturbate while I listened to his heart, to check his cardiac response - similar to a exercise stress test.

Yes, I'll listen to my heart while masturbating. We'll also use a teaching stethoscope so me and my partner can both listen whilst I'm pumping away. 😉

Collins speculum in place, opened wide, vibe on clit works very well for me.

Oh yes, but only at home alone while thinking about an upcoming exam or afterwards, reminiscing.

I do play online with someone who works in a medical facility and sometimes she will go to a private locked room while we play and masturbate herself... as I do the same thing.
