Do men think saggy breasts are ugly?

Personally you should keep it on until you marry a guy or you'll likely have a relationship based on just sex. That makes for an awful marriage. BUT, yes men do have likes and dislikes about breasts.

The under 18 year old that responded is a child. Men like most breasts. The most important part is the nipple, since that's what our mouth heads for.

Women are their own worst critics. Relax. If a man isn't attracted to you just because of your breasts keep looking around. You haven't found someone that really cares about you. We're dogs and like breasts big or small, perky or saggy.

Saggy breasts are only ugly if they get dusty through dragging along the floor.

Saggy breasts can still be fun and attractive. But there is a limit to how far they go down though. If they sag 6 inches, then that's a gray area (probably ok). But if they sag 1 foot, my enthusiasm dies.

Well if he's going to bed with her, chances are he already knows about the breasts. So, surely he is okay with them.
But for many guys saggy isn't attractive.

No men don't like saggy breasts... and no don't keep your bra on during sex, take it off. I'm being totally honest.

Although at first look saggy breasts are not as pretty as perky breasts, I never like it when a girl leaves her bra on, and I always take it off cause I love to play with them. If you feel insecure about your breasts, maybe you can leave your bra on, and then see what the guy does. Many girls do this, and when I ask them, 'aren't you gonna take your bra off', they all say, yea, but I don't like my breasts....and most of the times, their breasts to me are just fine, but girls are never pleased with their bodies.

Personally sagginess runs in my family because of this I didn't want to take the chance so I go to the gym and exercise that area. That works great! It not only keeps sagginess away but it makes them perkier and they appear bigger! It's great!
