Seconding Lance — gay dating norms differ from mainstream apps, and that's held true for me on gay dating sites.
The thing I look at first with gay dating sites is if the 'last active' timestamps does anything measurable — worth checking before you commit to gay dating sites.
Whether messaging is free changes everything, and that applies to gay dating sites as much as anywhere.
If if the match algorithm is honest about what it restricts — worth checking before you commit to gay dating sites isn't there, I don't bother with gay dating sites at all.
Worth a look if you want a comparison point — Luvdate handled gay dating sites better than I expected.
