( sigh ) ...
First things first ... you gotta accept the fact that Hentai will not last in your life, and that it will never satisfy you the way it is meant to be. try and get social and get to know a few people and maybe girls will come along the way, if you already know some girls then just politely ask them for a date and then ask them for sex, in some weird cases girls will accept that since they too, are longing for it, since it's normal to have desires for it.
I feel sorry for you if you fapped to thousands of doujins and it doesn't give you that kick anymore, you maxed out man, time for a new chapter,
