It's just so, um, emasculating...
Hence my comment about the poor bloke trying to pull at 15.
I mean, it's not that one should strive for masculinity by any means. I come from a very, very metrosexual family and my brother is gay. Alpha male-type bravado is vile.
But... really... Bear?! Big old, fluffy soft teddy bears, that you normally find scattered on small children's beds...?!
I mean, it doesn't exactly conjure up 'James Bond' in the suave, sophisticated, wooing-the-laydeez stakes, does it?
To compound it - can you imagine standing up in front of your friends and loved-ones on your wedding day, opposite someone who you'd quite like to respect you as a human and, err, a grown adult man, and say, 'I, Bear, do solemnly declare...'?!
Honestly, I really don't think it's the 'unusualness', per se, that is generating the reactions you're getting from people.
