I mostly sleep on my right side. The ear stud in my right ear has a rather nasty metal butterfly retaining thing, which has been digging into my earlobe and has left a nasty wound.
So I’ve moved the titanium ring into the right ear, and put a stud back in the left. I’m going to see if I can get another captive bead ring in Harvard Square; the left ear should be able to cope with a 16 gauge now, but I’m not sure what ring diameter I want. I’ll have to see if 3/8ths will work; 7/16ths is slightly larger than I like.
