I would still go with FetLife and start chatting in groups. Don't necessarily focus on asking how to find a partner; just be social and see who you get along with. You will have to work at it. In-person munches are the best, but they still require a lot of work. Finding people you click within groups will take even more work.

Feeld is okay, but like Alt.com and Collarme.com the only women I know of on there are professionals too cheap to pay for adverts/websites. (I personally find that distasteful and deceitful, but I live on my high horse.)
