Very good question!
I somehow think this is what makes Lycra /spandex fetish comparing to other ones such as leather , latex etc different.
The Spandex community is less big or often does not show officially. A lot of guys , in particular thongers do wear their gear for themselves but dont or cant admit this in public and YES we all wear spandex cause we love the feeling but we all (I assume) would loce to share this feeling as in talking, showing off and sharing moments wearing the gear with others, not even with the goal to fuck or to suck a cock , just to show off together in gear , hetero straight or bi men....
For me the best would be just to have a casual saturday or sunday full day gathering with others only wearing lycra , having drinks, showing off , sharing our experiences etc and wanking or touching meanwhile their own bulge if gys feel like it....
