For a while now I haven't been able to reach climax while having sex with women IRL.
Until about a few ago, I watched porn constantly and jerked off around once or twice a day, and in a very specific position.
This lead to my inability to focus on the sex itself when I'm with a woman, and I often found myself losing my erection in the middle of it.
I am in my early 20s so I am confident that it is my past porn and masturbation habits that lead to this situation.
I posted on /adv/ on 4chan about something like this around a year and a half ago, and received some good advice, but I seem to have lost it now.
What can I do to start enjoying sex again? How can I focus on the sex itself instead of having my mind wander?
Note that I have already stopped watching porn and have gone down to masturbating once every couple of weeks, and in a normal position instead of the usual one where I had to cross my ankles and flex my leg muscles.
Please help, you're my only hope.
