What are your thoughts on veiny arms?

So I have pretty veiny arms and am quite self concious of them, but one of my friends noticed and said she found veiny arms sexy but that's coming from a straight girl. What's your opinion, gays?

Edit: So to clarify, I don't work out or anything, I keep fit by biking and climbing, but it's not like the veins are about to pop out of my body or anything
