And not getting matches on tinder doesn't necessarily mean you aren't photogenic. When I used it I didn't get many matches either. Later I went on a trip and swiped through Tinder out of boredom, I suddenly got a lot of matches. Not very helpful because I went back home the next day. I think it's important to remember that Tinder varies the "exposure" you get by a lot, for seemingly arbitrary reasons.
@OP Easier said than done, but try not to make too much out of this. I think the recommendation for doing some activities with others is a good idea.
