I hadn't considered using rubbing alcohol for anything other than fire play.

I have, however, used mentholated rub on nipples or other areas to create that intense heat sensation when playing. But, mentho rub should not be used around the pink areas of her body i.e. inserted into the pussy and is messier than rubbing alcohol. A very small dab of mentho on the clit is exquisite torture, but again, be careful it doesn't get into the pussy.

(Is it in bad taste to say pussy here? )
