I think it' HOT! No doubt about it! :)
Well, I don't want them as defined as a guy's 6 pack, but a nice, smooth, taut stomach is amazing.
too defined isn't for me but tight flat abs I think is hot.
If she has some nicely toned abs, that's hot as long as she has toned legs too. But if she's like aiming for the strongest women, that's not good. Don't go too far because all those lines and cracks look bad on women.
I like it when she is toned it can look so sexy.
Depends on girl but it should be lightly
I guess it depends on how flat the tummy is and if the abs looks nice. I mean extra cut like a man is kinda gross!
It's not really that important a think for me. Just so long as it's tight and smooth it's all good. I like a girl to have a nice pair of breasts and that rarely happens on a girl with defined abs since somewhere along the way to getting cut abs, she loses her breasts. That's not a good trade.
Depends... I prefer a woman's belly to be smooth.
Not my thing
I think it's alright. It can be pretty cool. Definitely impressive. Sometimes a little intimidating, though, and I don't like them to get TOO hard, myself, mainly because I'm attracted to soft. When I think hard, I usually think "masculine". Still, that's not to say that if you're hard you absolutely look like a man. For example Piper Perabo has a great set of abs, and she's still feminine, and sexy. (Though Google image search is utterly failing to provide me with a good example, right now.) But yeah, I think muscular abs can be sexy, within reason. So long as they're not TOO hard, and the girl still has a curvy or feminine figure to balance things out.
But that's just my personal opinion. Other guys might disagree.
