Breasts are an erogenous zone for LOTS of women.
What does that mean? Stimulation of the breasts are connected to stimulation of a woman’s whoha, aka her clitoris. Want to get a woman extra wet, for both of your enjoyment- during foreplay and sex spend a little extra attention on her breasts. Thank me later.
 

A woman can orgasm from nipple play alone.
Though no one sexual fact is true for all women, for many, nipple stimulation is all they need to gain their first orgasm. You can help her get another one or two after that. So spend more than a couple minutes until they writhe with excitement. 
 

They need to be supported. 
Those with more, need more support from their bras. These bras can be just as sexy- just a bit more material. So get like the kid in Shameless and practice undoing them on your off time, because you never know what you will encounter.
 

They are NOT one size fits all.
Just know that.
 

Men have breasts and nipples too.
Try stimulating them and see how he responds! Nipple stimulation can increase a man’s arousal too!
