Often, the next time I'm alone and getting myself off, I'll take his cum stained briefs and just the smell gets me wet. I'll remember feeling the powerful splash of his semen deep in my ass, and the eroticism of us both kissing and waiting for his load to finally drip out. Often, he gets hard again from this.
Women are far more graphic than men sexually - we are just called whores if we openly discuss our lust.
On a real plane, i understand your fetish to use past exploits as fantasy for masturbation(possible future exploration). Scent is powerful, so much so that it can remind you of a long dead relative that you knew as a very young child. Scent can remind you of tastes, visuals, and even of sounds, possibly even certain touches.
With every load of semen having a slightly different scent, i can kind of understand your want to save the scent of your memorable conquests.
I personally am like a dog, i dont forget a scent. It is one of the few strong senses i have left after almost a decade of being an aircraft mechanic. Thinking about the person kinda makes me smell them out of thin air. And the thought and smells put together make it so much more real. At that point the only hindering factor is the fact that a hand or toy will never feel what i see and smell
Sorry at this point i see you as an anal conquistador, just on the receiving end for the most part. I cant wait to hear some of the stories you have.
By the way I also see that if a woman speaks openly about her sexual preferences is easily seen as a whore, say. But this is a sad traditional disadvantageous behaviour: everyone should be equally listened to and respected. As long as one support his speech with consistency and logic, any thought is welcomed. I personally love listening to female tastes on anal etc. too!
I enjoyed feeling my cum inside her when we would have those super sexy days/weekends when we would have lots of sex and I could take her ass several times during the day.
