Are women's breast erogenous zones? Or to put it another way, does nipple play of various types add to a woman's excitement during forplay?  I know I sure love to do it, but do women really enjoy it?

Yes, they are, jon54,

The areola and nipple are made from human tissue that is vascular with erectile capacity. Most women enjoy nipple play and some can even have orgasms from having their breasts and nipples manipulated. A minority of women, however, have very sensitive breasts and nipples and may find too much stimulation painful or uncomfortable.

Play around and be sensitive to verbal or physical cues,

LG, as always, thanks.

As with all things, people differ. The sexiest woman I ever spent time with had relatively insensitive nipples. My ex-provider friend can orgasm from nipple play. The same is true for men. I have very sensitive nipples and love for my partner to tease them.

One thing to keep in mind is that, like the penis, nipples can become more sensitive with too much play.

MMMMMMmmmmmm. Nipples.

The best advice I read was "don't act like you're trying to bring in a weak FM station on a hilly road".

a man kissing/licking/massaging/playing with my breasts is somewhat exciting to me if he is really into it and aroused by what he is doing, but the actions themselves do nothing for me. it is like someone making out with the inside of my elbow...not a turn off but not a turn on either.
