Just because people cringe at some information doesn’t make the whole thing dehumanizing. You’re right though that most people don’t want to know how the sausage / burger is made...
For most people it's not really that extreme and to some extent this has to be allowed for. That's the tricky part especially with sex, you want someone who is good at it, but that typically comes with experience. That may make some people uncomfortable. Find a good balance and just call it what it is, young people living life. But it's also a good warning to not "over optimize" and spend all your time going down that route because then some people would rightfully question that kind of behavior. I know I don't want a partner with thousands of sexcapades.
My experience is different. Not very extensive, so I don't want to generalize it... but what I've learned is, that experimentation (i.e. systemic approach to exploration) trumps experience. It's true what they say, "every woman is different" (well, maybe not every, but there's a surprising (to me) amount of variance) so what works for one doesn't (necessarily) work for another. I don't think that experience (as in each additional partner) has really given me anything except maybe confidence.
