It varies on the guy, but I feel most men do not like to show PDA.
Sesshoumaru shows some affection to Rin
yeas because in some episodes she shows affection
public displays of affection like kissing, touching people on the head
Well it's probably a bit embarrassing to be tickled and then have a laughing fit in public... Your friend is probably only feeling a little self-conscious and perhaps just doesn't like public displays of affection. The fact that he/she lets you tickle them at all shows that he/she does like you :)
It's the same reason that little girls tease little girls that they actually like. It's generally an inverse reverse manner of showing affection. In general, girls are more feeling and exressive of feelings and that's a charming difference, and boys admire it, but instead of saying that, they tease. It shows affection without risk of rejection. Sometimes backfires, but that's what's happening.
I feel like there is nothing wrong with kissing in public. If people don't want to see it, then they don't have to stare
I only call people I like and are special to me "Honey". I think it shows affection.
when girls/boys like eachother
Some girls just show affection in different ways. Like when boys tease they are trying to get attention, its the same when girls hurt.
Because it shows affection when a guy gives something sweet to the girl. Its like saying I LOVE YOU and YOU ARE SWEET.
He or she shows no affection towards you, rejects you in some sort of fashion and other sort of things such as rejection.
Boys like messing with girls heads because they think it impresses girls and it shows other guys to back off.
