I've had the buyer's remorse after sessions a few times. Sometimes it's my fault. We guys think we're horny when we're really not, which may really mean we just have too much free time and feel compelled to fill it. Or maybe I ate too much bullshit and the wood wasn't what it needed to be to make the session great (there's nothing worse than being with a girl that's FINE AS HELL, but the wood is like ehhh!). Or if it takes to long to release, the pressure TO release starts to build, as you can hear the minutes peal off the clock, getting closer to time (thinking, 'Dammit! I shouldn't have rubbed out that one extra time leading up to this session!).
Sometimes it's the girls' fault. If you're well over the weight of your pictures, or even well under sometimes (yes, I've seen girls that have lost TOO much weight), that's a total buzzkill. Some guys have the ability to walk away. Others (like me) not so much. Once inside, if her attitude isn't welcoming or it's off-putting and distant, that's a wood-killer, and definitely leads to a buyer's remorse scenario. Trying to put a condom on a limp dick. Yep, buzzkill. I mean, do you NOT FUCKING KNOW HOW to stroke a cock (say, with a bit of lube) and get some life into it??? THE FUCKING PACKET SAYS YOU'RE SUPPOSED TO PUT IT ON AN ERECT PENIS!!!!
How hard is this shit!! No pun intended.
Lack of freshness. Buzzkill. Woodkill. Buyer's remorse, most definitely. Ladies, even if you just fart after taking a shower/bath, freshen up before we get there. That fart air is now lurking near your starfish, and once we get to doggy style action, it might possibly find its way out and onto our nose hairs. Not cool. This doesn't include that burnt condom/high friction smell that comes from using Trojans. I would rather see a woman that's just OK looking, but smells fantastic over a hot chick who smells like she ran 3 miles before the appt. Baby wipes DOES NOT replace soap. Hell, I used to use them. I stopped because I didn't feel fresh after using. I keep soap and a cloth in my car. On the way to a session I'll go into a convenience store bathroom and freshen up rather than go into an incall not having showered if it's been an hour since I last did, or if I'm noticeably not as fresh (self check, if it's borderline I freshen up). And not just the dick, balls, and ass, but armpits, neck and shoulders (from the top, working my way down), anywhere that her mouth may end up on me, I want it to smell like soap's been there (no mouths on my armpit, mind you). I expect the same from the ladies.
Bad locations can create buyer's remorse. If a bunch of thugs and creeps are swirling around, it's not a good look. Even if they aren't associated with you, it gives the impression that at least of them might be a pimp on the premises. Could be yours. Maybe not, or maybe.
Not all sessions are going to be perfectly smooth, but when 'defects' in the process are exaggerated, it can make for a forgettable day.
