It's not like a balloon you can blow up to keep it firm and bouncy. Breasts contain mostly of fat so they hang and when we get older the skin will lose it's stretchiness and the breast will sag. There is no "cure" for that. It's for the same reason the skin in your face will sag and everywhere else on your body. If she has also been pregnant and breastfed, the breasts became bigger and the skin is stretched and then they go back to normal size after stopped breastfeeding and the skin is then stretched out and can not go back.
If that is what both parties agree as being okay.....than yes a man can suck on a woman's breast.
Because it arouses him and makes his love making blissful for him and the woman as well.
So that they can show their man how sexy they are! And also that boys can touch them
Well, the first step would be to be man who is appealing enough to a woman that she would even want you sucking her breasts. Once you clear that hurdle, just let her tell you what to do.
However you want. There is nothing you can do to harm the breast unless you bite her.
no
It is not advised to do this.
Yes, assuming she is in reasonable health
they look at the females breast
Only if you suck too long, you can cause over active milk glands which will cause your girlfriend/wife/play buddy to wear nursing shirts, even then it can soak through. Also if you bite, you'll get slapped.
It would be absolutely impossible to get near a woman's ovaries. They are well protected in the lower abdomen.
A woman would love to suck a 5.9 inch penis because she knows that it pleases her man.
