I've been really wanting to sell yaoi comics too but I can't figure out a viable way to make money without giving out my fucking SIN number. Gumroad is a good place to sell NSFW work, as they deposit directly to your bank, but they require your sin number to do this so I was too sketched out to sign up.
Only other option is to use a service like payhip, patreon, or
itch.io that allows nsfw but processes payments through paypal. Using paypal is a fucking gamble, though. You can get away with using it for nsfw, but you run the risk of your account being shut down and your funds taken by the company at any time, should you be caught.
