lol Right! You'd think they'd get used to the sex by the 4th or 5th time at least, but no...
WELL, in my opinion... seme who cries are... epic and I likey.. D:< Umm, how do I put it, I mean I'm like those type who enjoys seeing a particular group of people reacting differently than they usually do. So, when a seme who's been holding his feelings really hard, and cries, I feel like I'm standing on top of the mountain (happy~).. *W*?? But as you said, I just can't stand uke crying, maybe because they're weak or something... and couldn't hold their feelings for a minute.. I can tell earnestly that I'm an uke, but I just don't cry, I just have a bad-bad-bad temper. So... yeaa.. w.w Seeing small uke cries in an anime/manga, makes me feel like I've been pulled to their level (though I know not all are like that)... Which makes me confused, how can a seme likes an uke... who behave like that... ;A;
I have semes that cry. I think when a seme cries, it's so rare that you know this guy is really feeling something emotional right now. It shows a vulnerability that's just nice to get a glimpse of in such a personality.
Haha that's the way I like to see my men (both semes and ukes) cry. I do like writing crying scenes and I lavish a lot of attention and detail on the (probably 'cause I'm a crier myself....), but the key to doing it well, I think, is not doing them frequently. Every time during sex? God no. But during the story's emotional climax? To see a previous tough character break down in response to their hopeless circumstances, with only their lover (seme or uke, it doesn't matter) able to save them - I find that so beautifully visceral an experience. Yeah, I have no idea what I just said there. It sounds right though.
