Idk, the health thing is the hardest thing to control, at least from my perspective. Like in fantasy land the whole even sounds awesome. Cover a woman in cum (bukkake is not limited to just face) In reality not so much. The smell, Taste (you don't know what those fuckers be eatin'), acidity. Those alone make it suck. Then the mess fa ctor. You could do it on a tarp, a very unsexy , noisey, not so comfortable tarp. maybe an air mattress would do. You better hope cum doesn't zip right over you. Depending how many guys you have, the fly away spurts may be a pain to clean up.
... If you do it on a bed or any type of fabric... say goodbye to it unless it's machine washable, kiss it goodbye.
Now other issues. Performance issues. Early cummers, Mid cummers, Late cummers, no cummers. Are you going to be able to get the guys to cum at about the same time or very shortly from one another? What if one guy takes an hour to cum and another dude literally cums in the first 30 seconds. Some of the guys may not even be able to get hard in that situation.
Hope you have eye drops. I imagine more cum than anyone would like, would get in the eyes.
How are you getting the guys off? Blowing, Handjobs, anal, PIV? Are you going to make the wear condoms. No condoms? What if they don't pull out. What if they don't want to use a condom. Perhaps they decide they want to fuck you instead. Maybe you get sore and want to take a break, but another guy that hasn't had his turn still wants to despite your wishes. Hell maybe you didn't want to fuck them period but they decided they are going to anyways Now we have a potential rape/gang rape on your hands. Unless your husband is a super badass, I'm pretty sure 2-4 dudes is adequate to take him down especially in close quarters like a hotel or a room.
Maybe you find out you don't like bukkake after all, then you want to stop. Sucks for all the other guys involved. Now every one is disappointed and bummed out. What if the husband gets jealous, or doesn't want anything to do with you after the event?
Now the STD's roll in. How are you supposed to realistically make sure they are clean? I doubt you want STD's anywhere in/on your body.
These are just a few problems that could crop up. Some are grave, others are mild, and everything else is in between.
Maybe it goes over fantastic. I just know the Pros don't outweigh the possible cons.
<.< if only fantasy was so much easier to obtain lol.
