Lisa,
Probably the best way I can think of is to arrange for
him to "accidentally" see this website. If you don't like his
reaction, he obviously isn't good enough for your treasures.
If you initially get no reaction, you could bait him by asking if
he thinks that's sexy because you do.
If he passes the test,
you could then, if you so choose the lush garden of unspeakable
pleasure that awaits him if he plays his cards right.
XOXO

don't mind me asking.
