I don't think it's something they really have a choice over. Remember that they basically radiate demonic energy. All mamono do, which is why any region that has a lot of mamono turns into one type of Demon Realm or another. So, assuming I've got the logic of the setting right, eventually even just being 'around' monsters will turn a man into an incubus, even if you assume that somehow or other he's maintained his self control enough to not have sex with them.

Basically, I don't think they(or any other mamono) can control how much DE they release, but I'm not 100% certain. ...Maybe someone who reads and writes Japanese can drop the question to KC on his Twitter? /hopeful-look-about
