I'm amused, alba, because what the typical woman thinks is looking sexy is far from what a male, other than, perhaps, a young adolescent one, thinks is looking sexy.
lol Fred, that is one question I have not asked my adolescent sons
'Hey guys, what do you find sexy in a woman?'
Apart from one blushing and the other telling me to go forth etc, etc, I'll never know the answer :-D
Some women think that big boobies is what is appealing to a man, other's their face, others their personality. It's just a mish-mash of everything really I s'pose x
At their age, alba, your sons will find almost anything related to women, such as an innocent advert for lingerie, sexy. They'd probably find such adverts in The Lady sexy, let alone the ones for nannies and au pairs. Phwooar !
