Male erogenous zones: nipple stimulation and erection?

Does anyone find nipple stimulation highly arousing, especially during foreplay?

Kissing, licking, sucking, biting, touching, tweaking, tickling, twisting, pulling, tugging, massaging, blowing on, pinching, putting ice on, nibbling and clamping my girlfriend’s nipples during foreplay always gets me aroused.

yes :) Do you?

One of my ex-gfs used to bite my nipples. Holy crap that was pure hell and ecstacy at the same time. My wife doesn’t do it.

<thinking that maybe I should have her start>
