Finally really getting started - finding my core masculinity

Hi guys,

first of all, i hope my story won't be to long

i'm not completely new to the whole NoFap topic, i read about that concept in a book about manliness maybe 1,5 years ago and already tried to avoid masturbation a few times (i think my record was about 25 days or so). Often when i'm busy i get along easily without fapping for a week. Avoiding porn was not really difficult for me, but sometimes i just come back to it because of laziness.
But my actual, big problem is not porn or fap addicition, but a general difficulty to find contact to my masculinity. I am nearly 24 years old and i never had sex or a girlfriend.

About 2 years ago i began to deal with the whole "How to be better with women" topic. Just at that point i truly realised the core of my problems: Shyness, miserable self-esteem and also a general lack of sexual experiences from my teenager years when i didn't have many friends for a few years. Then, after i read my first books about dating and self-confidence, i recognized my progress quite quickly. My first dates with a girl in summer 2015 weren't so unsucessful, although i was very unconfident and nervous most of the time. Maybe it would have been even enough for a relationship if she didn't meet another guy who was interested in her exactly at that time (dammit).
After i overcame that, i continued working on myself.
In February of the last year i was dating another girl who was quite open-minded. We ended up in my bed on the first date, so i was kinda nervous, and as we were about to start, my erection was gone and i wasn't able to get it up again. I met her a few times after that, but the whole thing came to nothing. I tried not to obsess about my "sexual failing" and i know i'm not the only one who experiences this. But of course this wasn't the best experience regarding my sexual confidence.
Today i'm still working on myself, especially concerning my mental self-esteem and confidence. But now i also think that male confidence develops from a healthy masculinity, and that NoFap can help me to move towards that "core confidence".
Considering my previous experiences with avoiding masturbation, i think a 30-day-challenge, will be a good start for me. If anyone wants to join, feel free I'm gonna start the challenge tomorrow.

If you made it until here, thank you for reading my whole story! Sorry if my english was not always correct. Looking forward to your own comments and opinions!
