Social restrictions do not trump biological functions. It’s often said (mostly among PUAs) that attraction is not a choice. There are many things that are not choice, but what we do have control of is our actions.
I do not fault someone for being attracted to a relative. I do fault someone for acting on that attraction.
We see attractive people everyday, and most guys, if it weren’t for social restrictions would probably try and have sex right then and there. But society is a factor, and thus guys will go through the necessary courtship rituals instead. It’s the same thing, except here, there is no socially acceptable process by which those feelings of attraction can be shared.
It’s our rational mind, and therefore, our social upbringing that dictates that family members expressing sexual interest is repulsive to you. If left to natural devices, or if they family members were somehow separated at birth, or it is otherwise unknown to them that they are family and the proper behavioral sets that accompanies that knowledge, it is entirely possible that those two people might find each other attractive and pursue sexual relations.
Somewhere out there is a relative of Pamela Anderson, and if they did not have knowledge of her being their relative, would most likely drool over her videos and pictures like every other male youth has at one point. Hell, they probably saw a hot woman before they realized it was their auntie or niece.
Either way, as stated before, whether the results are favorable or not, we want to see reports. I think it is clear to everyone that sexual responses from family members are not favorable, and that reports of such behavior does not imply appreciation of said behavior.
As a bit of an aside, I think people who are immediately repulsed by the idea of using pheromones around family have limited perceptions of what pheromones can be used for, and to a degree, is reflective of their intent regarding pheromone usage. This is to say that some of the users on the forum clearly have sexual expectations regarding pheromones, and thus, would be repulsed at the thought of bringing the pheromone world and the family world together. Of course, it goes without saying, there is nothing wrong with such perceptions, but it is limited.
Personally, I use pheromones around my mom when the chance permits. I used pheromones at a cousin’s wedding. Contrary to what you might believe, my reasons for wearing pheromones had no basis in sexual desire. I use pheromones to improve my relationship with my mom, IFM and IS goes a long way towards improving her mood. When she is happier, it makes it less stressful for me, and thus, our relationship does not suffer unnecessary stress. At the wedding, I wore IG, p74, IS with the strict intention of making the best impression I could make, to make sure that I represented my direct family as best as I could, despite having been raised in America. It was probably the last time my extended family would be meeting in a long time, perhaps ever. It was definitely one of the last times that I would be able to fly to Korea for such an occasion.
Those are just two examples of how pheromones can be useful around family.
