I was on the way home from an encounter and had to take metro (the visit was downtown). At the stop I guess they had bomb sniffing dogs being trained or something and as I walked by the dog started to bark, the officer asked me to stop and I did and she said do you mind if he sniff's your computer bag which I was carrying with me, I said sure, but the damn dog left the bag alone and went straight sniffing my crotch!.  

The cop (female officer) sort of smiled and pulled him back and I said, I assure you officer, I am not carrying anything worth noticing there .. she laughed the damn dog kept on barking and I left wondering if the fucking dog knew I just had sex about 10minutes ago or not!..

Can dogs smell that on you? next thing we will see is sex-sniffing dogs in hotels

OMG, LOL thanks for sharing such a "funny" story. The safest thing is to take a shower after the encounter...but then again, "I" can understand why one would leave the after "taste" (smell)- now, from a guy's (my)point of view (maybe some guys would not agree), it's a way of relishing and appreciating the wonderful time spent with that special someone. The scent of a woman is so visceral and enticing IMHO.
But then again, perhaps you had to rush to the office...oh well, am glad nothing happened to you.
Thanks for sharing. Hobby on!

After an appointment I put my condoms and wrappers in a zip lock bag. When I go into work I throw the zip lock bag into metro trashcan.

no link to do some human testing!

We need to test to see if the canine nose is better or equal to a human nose.  Yet the original poster doesn't have a link so I am unable to test the hypothesis.  

When I come home from a session and go by parents house, my parents dog will also go right to my crotch to smell me. I thought they knew more but was not sure. I figured it was female dog thing.

I always wondered if guys that are married always shower after the session. we all know that if it was an intense session that wonderful aroma of sex is attached to us.

I knew that when my ex-SO would grab a quickee at lunch, the wonderful essence on a hot summer day would stay with me (uhhh. smell my fingers?)and I remember a lady smiling as if she knew. Leaned to shower after those quickee sessions.
