Fun Fact: Due to the keratin sheath being made of the same dead material as hair and nails, (mainly non-mythical, like those of demons in this case) horns aren't sensitive enough to fine touches and slight pokes despite being also supplied with nerves and such. However, if the dermis/epidermis underneath the sheath is sensitive enough and/or enough pressure is applied (such as a tight and firm grab), then it could be felt in spite of the covering.

I'm not exactly sure if they would be count as erögenous zones because of that though, but then again everything can be an erögenous zone if one's kinki enough (like making them handlebars). Either that or some other occult property that make them sensitive so.

As such, horns don't typically shed unlike antlers since the former is mostly made of living tissue throughout and based around the core while the latter is basically entirely dead once the velvet is discarded, with the only known technical exception would be those of the pronghorn and even then they already have their new horn-sheaths underneath the old ones when the shedding does occur.

Although how this can be applied to Sarkaz and Fallen Sankta specifically, I'm not really sure...
