This question depends on where your at. Personally I think they are g@y but I am living in Colombia. Here they cost like $2.50 US and as a business man you are almost required to get them (its like brushing your teeth staying well groomed). I still feel stupid every time I do it but "when in Rome" right? The ladies have actually complimented me alot on this and seem to like it.
My girl really wants me to get one. She thinks it would be fun. I don't have a problem with the idea of getting a manicure. It's not much less feminine than getting your hair cut at a salon. My problem is, sitting in a room with intense fumes while a lady messes with my hands for an hour doesn't sound like that great...
