Hi emre

Don't be influence by the media or societal expectations. You would be surprised but there are many women and men in their 20s who are still virgins. Back in my 20s I was a virgin at your age too so don't stress. In relation to porn used for masturbation, sometimes it can be used as an avoidant thing if you have intimacy issues with the opposite sex. I suspect you may have psychological issues pertaining to a deterioration in your libido/erections. Do you see a therapist? It may be good to continue a discussion with one so as to explore what underlying issues there maybe pertaining to your sexual issues.
