A simple half-hour shoulder and neck massage is a good start for a spa "virgin." A little time to soak in a hot tub or relax in the sauna might do him some good, too. Tack on a harmless mani/pedi if you keep getting scratched in all the wrong places. Give him a gift card for a professional shave for the ultimate masculine luxury. He'll love the hot towel treatment and close shave, plus he might find a few products that streamline his own regimen. It would be ideal if you or your man can tour the spa facility and ask questions before scheduling treatments. You can discover whether there are men-only facilities, if therapists can be chosen by gender and what the typical attire of the facility is before committing.
