I want to start dating again

Do it by thinking like a woman. That is, you look for sexuality by having some plausible deniability that you're not looking for sexuality. So give dating sites a miss and find sites that are centred around meeting people but which don't include s*x or dating anywhere in their description. Hellotalk is one that's superficially about language learning for example but the developers know exactly what they're doing and match you almost exclusively with the opposite s*x.
