Question pertaining to me.

I (31M) know myself pretty well. I've been around the block enough to know what I like and how I operate. But I don't have a name for it.

Does anyone here have a descriptor for "Not Ace, but also can't be assed to seek out encounters"? Like... if it happens it happens, and it's great when it does, but I can go years between hookups or even relationships with no emotional hang ups. What do we call this?
