lol!
Well having just cashed in the spa gift certificate I received for my Bday some months back... I have to say I don't know how anybody could not enjoy an experience like that, male or female, Mmmm...
Personally, I don't have issues with men who use skincare products, indulge in spas or manicures etc. However (and I view women's products this way too), I really dislike it if whatever scent he is wearing arrives 5 minutes before he does and lingers well after he departs.

Scents should only be really discernible when one gets within kissing range...
Stuff that is subtle and made with mostly natural ingredients is nice though...
Regarding the time one spends on nails, hair and so on... well I have problems with women, let alone men, who spend forever in the bathroom
Making yourself feel good with the products you use is one thing... excessive vanity is quite another...
