As far as I can tell it addresses the mechanisms proposed by the parent comment.

If the claim is specifically about reduced stimulation during sex, that's a different claim. I'm simply saying the initial explanation seemed like bullshit

In general, if a claim is easy to verify, someone has verified it, but the US is also somewhat prudish so making the research more explicit might make it less likely that the research happens in the states. If there is an existing study that says this claim is correct, feel free to link it.
