Returning to the original topic of the thread, about frisking, I once had a rather funny incident, but I think it had more to do with general appearance, than with the cock or bulge per-se, although I'm sure that was a contributor.
A group of 5 of us were flying out of LAX on the way to a fetish event (this was in the pre 9/11 security days). My boyfriend at the time went through first, and the rest of us were on the same line behind him. There was a woman security officer stationed at the metal detector. I'm not sure he set off the detector or not, but perhaps because he was wearing army fatigues, my boyfriend got a careful wand search by the officer. This apparently caught the attention of the male supervisor, who was standing a couple of lines away, observing. The next three guys on line, starting with me, had a sort of biker appearance- heavy engineer boots, scruffy Levis, and heavy leather jackets, etc. As I see the woman finishing up with my boyfriend, I step up to the metal detector, and am waiting to make eye contact before stepping through. However, just as I am ready to step through, the supervisor, running and waving his hands like some flaming queen, dashes over, shouting "I'll do them! I'll do them!" and shoves the woman officer out of the way. I step through the metal detector, and of course it goes off (metal in the boots; this was before the shoe-removal days). The guy then begins a detailed personal search. However, he doesn't start with the wand, but begins directly with a pat-down. During most of this, he is kneeling, with his face at crotch-height, paying careful attention to checking my legs and boots. He asks me all sorts of obviously security-related questions, like "What size shoes do you wear?" After I answer "Fifteen," this seems to demand another couple of very thorough inspections of the lower half or my body, before I am allowed to proceed.
The next two guys in my group got a similar, although not quite as detailed, inspection. The last guy, however, was waved through without even a glance.
There was a short up-escalator just after security. It took all our strength to avoid laughing until we reached the top, out of earshot of the security officers. After we all exploded in laughter, we began teasing the last guy, who had passed through unmolested. "Well, Mark, I guess he didn't think you were sexy enough to bother with!"
