I don't really agree with plastic surgery except in perhaps extreme cases. I think generally, if you're the type of person who feels they need to have bigger boobs/a smaller nose/a flatter tummy etc etc, then it's more of a self esteem issue than something being wrong with your body. Maybe I'm wrong, but I'd imagine in many cases of people who have plastic surgery, both men and women, that they don't turn around after the surgery and feel completely at peace with their body. Nobody's body will ever be perfect so I think it's important to love your body the way it is. I would find it a turn off if I discovered a man (or indeed a woman) had had surgery done. Except in the most extreme cases, it just says to me that this person has confidence issues. Even if they feel confident after the surgery, it just suggests that they're easily knocked down by little things.
I think everyone should take pride in their appearance though, at a healthy level, and that includes men and women. I don't have a problem with women using moisturisers etc so I guess I don't have a problem with men doing it either. Personally, I wear makeup but not every day and I can happily go out without any. I don't have a problem with men who wear makeup, though my opinion on that is the same as for women - if you feel that you can't go out without it then you're taking it too far. I've never felt the need to use such products. I use moisturiser if I get a spell of particularly dry skin but it's not something I use every day.
To sum it up, I don't have a problem with men who use such products, but I wouldn't find it a turn on. I suspect it may be because I know two men who do these things - one of them is gay and the other we can't believe isn't gay, so maybe I'm just conditioned to think that now.
