Thanks, LV but I tend to think that there were possibly a good number of unknown potential 'victims' who paid a visit to Dahmer's apartment but somehow managed to depart in one whole piece and for various reasons failed to speak about it to anyone after Jeffry Dahmer was arrested and accused of various crimes.
He killed 14 (?) but I'm thinking that there were a number of others who 'visited' that place.
AND .... Who in the hell woold live in that apartement now?
With all the crazy thoughts and desires going through his mind, and with those thoughts amplified by being in "cruise" mode at a bar, I'd have to guess his vibe would be very off-putting to even the fruitiest of gapers. On some level, it must've been impossible for him to extend himself in a positive way.
Generally, he'd lure guys to his place with the promise of beer and possibly drugs. Although it is true some of his victims were openly "gay" men (judging by appearance), and those must have been an easier mark with no demands other than an understanding there'd be sex. If anyone had survived Dahmer without so much as being assaulted, it would've been one of those types of guys, but I haven't heard of a credible account of that.
I don't know if it was possible for Dahmer to get off in any other way than what he was doing, quite frankly. From what I understand, it was frustration over that fact which caused him to kill his first known victim (a teenage hitchhiker, white guy btw, that Wizard of Truth mentioned) when he'd have preferred the guy just to happily remain in his presence instead of asking to leave. It's said he never looked back from there, and his sexual urges became set in stone from that day.
