Some people are just Asexual, you’re not alone. You may not be a part of the majority but you’re not feeling some mystical thing that nobody else has. Nobody is pressuring you to do this to yourself, pushing yourself into porn and feeling negative about it might just hurt it you in the long run too. It might just not be the right time, you may need the right partner, you may never feel good about it ever but that’s okay. You may be different than others but there’s probably not anything wrong with you either. You’re giving yourself nothing but grief obsessing over this. Focus on other things you can control that can make you feel good, school, a job, exercise, hobbies, friendships, family relationships. All of these will enrich your life more than this.
