I think the percentages on here can be viewed as subjective and can mean different things to different people, which was one of the reasons I left it blank for several years, especially given percentages of anything are not constant throughout time. An example would be that today one might feel they can lift 70% of their max on a lift, while the next time it might be 80%, only to drop back down to 70 or lower the third time, thus rendering ironclad percentages meaningless.
With that being said, I've settled on 1% for two reasons:
1. As I've mentioned here previously, my wife has admitted to me seeing me interact on some level with another man is something that might interest her and unlike in the past, I feel I'd be more open to the possibility if only to fulfill her fantasy as she has done for me with other women. While this is something we are not actively seeking out and more than likely will never happen, it is enough that I feel warrants the 1% as it indicates the door is also not completely shut. I also feel the 1% is representative of the fact I do post pics of myself here and I'd be naive if I didn't acknowledge the fact that 99.9% of those viewing them are other men, as much as I wish the female members were.
2. It has been mentioned on similar threads by other straight men who list 1% Gay, that doing so is their way of expressing solidarity with the LGBT community and the great members of all sexual stripes we have here and to me that is another reason I decided on it.
So, because of those two reasons, being "1% Gay" seems like a good compromise for myself and due to that, I think the most you (or any other gay man for that matter) could expect from me if we were to theoretically meet up is the same thing another straight man could expect: the potential for a platonic friendship based on conversation and shared non-sexual activities, with the addition of being with an ally who would have your back if you experienced homophobic hate. Nothing less, nothing more.
