When it comes to making moves you won't regret later (like the recent move I made into the field of do-it-yourself fisheries), the best advice I can give is to make the decision consciously and with a clear head, rather than at the height of emotion.
In your situation, that'd mean ignoring your throbbing lust, sleeping off your sexual frustration, awakening in the morning and calmly deciding whether you really want to take it to the next level with this guy.
In my case, it would have meant waiting until after the thrill and dazzle of do-it-yourself aquatic husbandry had worn off before ordering all these metal troughs and salmon eggs.
True, it may not seem spontaneous or particularly romantic, but you're more in control of the life you're leading, and that's generally a positive. Plus sex is sex--anticipating it is almost as fun as having it, and it'll be just as great (and somehow also awkward) the first time you shag this guy whether it's tonight or next month.
So take a break, do some pilates, then decide. Then on your next date, put your plan into action, either by downshifting the physical aspect, or dragging him to the floor and taking him on a magic carpet ride to your cave of wonders.
