Apparently he can have MULTIPLE orgasms now too. Which is just hilarious to me as I've been long suspecting the full body orgasms they describe are a weird interpretation of what happens when a natal woman has multiples.
Certainly not all women can do it, mostly do to how sensitive things can get after one, but 0 men can do it. The penis doesn't do it the way a clit does, and no amount of scientific fuckery with a dick can make it capable of it.
EDIT: A reply made me realize not everyone knows what is meant by multiple orgasms with women. Its not that you can climax again after doing so, which yes some men can do. But, you have to build back to the orgasm. Women can have almost a cluster of 2+ in quick succession after reaching climax immediately one after another. Some have mega issues with it because things get super sensitive and touching can be more painful than not. This is why Kevin can't be having multiples, his inability to have one aside, because its a magical power of the clit that penises don't have.
