I was at a gem show today and all the pink stones stood like crazy for me today! I personally don't have a preference for pink but something must be off today for me as all I saw today was pink!
I also have an uncle who is quite partial to it and loves the color to death for some reason, and he is straighter than mofo.
Based on those 2 experiences I would have to say you are defenitely 300% not gay.
Have fun at the wedding....!
