Tbh, my personal choice is that they should just be sorted between
cock sockand then
cock sleevebe left alone.
Maybe for things like this >>668860
but, the problem with that is that things like these >>943284 are actually referred to as cock sleeves sometimes (but definitely not as socks.)
So, the more correct option at least would likely be to alias
onahole(which is less ambiguous if a bit more weeby) and use
cock sockfor things that are more accessories rather than sex toys.
