Including other hobbyist?

I've never had a hobby buddy(not sure why any guy needs one?), but I've heard of guys throwing other guys under the bus for favors and such. Just expanding upon what you've already posted.

Be prepared to eventually get caught.  Even though you don't want to admit it women are smarter than you, more patient, more skilled, and just better at this than you can ever imagine.  If you're not caught, its just denial on their part or they don't want to go down that road.  I was caught and divorced, here are some tips to delay the inevitable.

This is how suspicion will be raised, and raising the radar.

Smells, women's sense of smell is better than yours.  If you can't take a shower right-away with YOUR brand of soap, fill-up with gas and  get a little on your hands, and touch the back of your neck if its within four hours of seeing your friend.  Don't believe me, keep  that shirt that you've worn that day, leave it in the laundry basket, and four days later smell it.  Yes, its that noticeable.

Habits: I pick up matches wherever I go for whatever reason, its my habit.  Picked up some a few times from some establishments that i forgot about but were still in my pocket.  Business cards, was given a card from an AMP for discounts after several visits, thought I had tossed it, but it was thoughtlessly tucked away somewhere it shouldn't be, but a place that I forgot.  Candy/mints, bottles of water, don't let habits or treats give you away.  Candy wrappers.

Another flag raised, the passenger seat was moved back in my car after a little afternoon romp, SO at the time sat down and was like why is this seat pushed back?  Said, my friend Brian was with me and I gave him a ride back from work - Brian is 6'2".  Always have a story.  I remember the Mad Men episode when Penny was trying to figure out how her boss was going to get out of it, but smooth operator had a story all ready and didn't even blink when throwing out his excuse  Always have a plausible story.  Women are passive aggressive and aren't going to confront you on it, unless its a shitty story.

The Truth - Always have a story and make it somewhat true.  Before your noon'er, go shoot a couple hoops, hit some golf balls, get a coffee at the mall.  If a question arises, you can answer truthfully.  "I called you at noon, where were you?"  You can honestly say, my phone must have been in my jacket pocket, I was hitting golf balls.  You can give a truthful description of the range, the weather, who was there, etc.  Bonus, you don't have to remember the story, because its true.  Especially when she'll ping you on it several months later and ask you again in a sideways fashion to try to catch you.

Burner phone is great, but you better have a damn good reason for having it when she finds it.  With the burner phone, always delete the call/text history, religiously.

Finally, situation awareness.  That mini-van look familiar?  It might be your wife, but more likely her friend who just wants to be helpful.

How did I get caught, spyware on the computer.  Started with me forgetting to clear cache/history and using personal computer

In regards to the hobby phone, keep it somewhere where it won't be found OR use google voice. Google voice has an option where you can put the do not disturb feature on and nothing will come through unless your ready to use the number then turn it off.  

I had a man who's wife called me cause she found his hobby phone. DUMB

If you have a hobby phone keep it in the same spot that you keep your spare tire. I knew of another hobbyist that popped out the interior frame of his car door and kept the phone in there.  

Shower, and WASH your face, brush your teeth. I have seen too many men walk out of the session without washing anything then go right home to their wives. Not only is that obvious, its gross.

I always take mine with me after an almost-disastrous experience.

Went to visit someone. Parked in apartment complex.  I was still new - always left my wallet and phone in the car because I "didn't want to get robbed."  30 minutes later I walked out and car was gone. Luckily I was able to get back in to the gurl's place and call the tow company and get my car out.  Blessedly the cabbie was understanding and happy to wait for me to get my car back to pay him. But it was a very frightening couple of hours.

Would have been a lot easier if I had my own cell phone with me and wasn't worrying about having no wallet, no phone, and no way to get home 10 miles from home

Women will pay for a private investigator, and have them track you every move....You will wonder how the fuck she knows all this shit. Is it a tracking tool on my computer, is it one of my boys telling on me, how can she know all this stuff, I covered all bases. Well check out your surroundings and look for a car that you keep seeing, you can bet she has a PI on your ass.

not carrying ID is in and of itself an invitation for trouble if stopped by police for questioning when coming out of a hotel or incall.   If you provide ID as legally required when asked by LE, and otherwise simply refuse to answer any questions,  and ask if you are being detained or are free to go, you are best off.

Not having ID allows LE to detain you on suspicion and further investigate in and of itself and is very unwise....
