Important.

The most important thing is to stay away from porn long enough to avoid comparing yourself to some "stud" who has the advantage of judicious editing, camera angles and a partner who pretends to love everything he does.

Seriously, if you worry about "not being able to satisfy" a woman, it will become a self-fulfilling prophesy because your partner will pick up on your anxiety. The fact is, every woman you might meet likes different things. Get over this "real man" PUA bullshit. Continue on your nofap journey, do the 90 days, then when you meet a real woman, take the time to learn what SHE likes. That will be much more beneficial to you in the long run than trying to compare yourself to some porn actor.

 

I agree with @Steel Fury. Intimacy is about connection and sharing emotions. It is not a performance, it's something the two of you achieve together.

I have met women who apparently thought they need to perform in some way, and I must say it turned me off a little. And I have turned off other women the same way, i.e. by trying to act like a "real man" instead of just being myself. Try to avoid that misconception!
