The whole body experiences the experience of sexual intercourse. All organs respond to stimulation and certainly one of the most erogenous zones, the chest. You have probably noticed that their nipples change during sex, but you do not know that not only that!
Breasts can change during sexual activity in all the forms listed below!
1.
They become more sensitive than ever.
2.
They are magnified.
3.
During that time, your chest "releases" fragrance through sweating, but most likely none of you will feel anything.
4.
The chest tells the brain to release oxytocin - known as the love hormone.
5.
They are a key element in achieving orgasm!
6.
Your nipples may change color (generally become darker).
7.
The feeling of pleasure in this part of the body is very great.
8.
You may notice nipple milk coming out (mostly if you are breastfeeding), or a milk-like liquid.
