It doesn't heighten jack shit. It WILL kill the pleasure for her eventually and then she'll hate sex. Why not just get a clip on and try it out for size?

My old boyfriend wanted me to pierce my clit so he could experience it and I told him I would if he got his dick pierced first.
He dropped the subject. Love and devotion went only so far for him.
