I find them really appealing (wanted them for about a year and a half) and they might even make your face more masculine. I'm not entirely sure, but I do love them. I'll definitely get them at some point.
Thanks for the advice Cynthia, Helena's "I had my right ear stretched to 5mm at the shop" threw me off a bit. How large are Sevan's gauges?
Lilac, I don't really think one ear piercing will "draw attention to me", and the place I'm going to is pretty reasonable (£8 per piercing), so it's not like I'm spending a lot. And I find that the general public aren't really aware of LGBT as much as we are, so I doubt they would make that connection if I had snakebites. I've also seen loads of guys with snakebites, (my cousin even has them) so I don't really find it unusual or something that would make you "stand out". I realise that I'll probably have to wait a few years until I can get them, and by then I'll know if I definitely want them or not, etc.
I appreciate your concerns though! But I'm already passing very well and I have enough clothing to last me a while.
