Brassiere said: You own more panties and bras than your wife does.- no wife but more than every girlfriend I've had
You've had the Salesladies giggle at you, after you tried on bras in the dressing room, then purchased them. - more than once and told once to "have fun"
You watch porn and are jealous of the females, who are enjoying cock. - since i was 12 yo
Lingerie catalogs arrive at your house addressed to you, not your wife. - no wife but yes otherwise
You've been called by your girl name, outside of your own house. - not yet
A few more:
You want to give women fashion or lingerie advise. Too many panty lines!
When you spend enough time in the lingerie section that store security checks you out.
When you dvr make over shows on tv.
You check out every guys crotch.
You see a woman wearing the same dress you have.
