Porn and my Relationship

Hey guys and girls.

I started my reboot yesterday and right now i am really struggeling and fighting with an erection that I cant get rid off...

I do this for my girl. She is a sweet one and since I started masturabting on a critical level my sex performance went down pretty hardcore. I ejaculate after 10 seconds (i was better before I started) most of the time and I am really scared I can´t get rid of this after all the time of extreme and secret masturabting and porn consumtion.

Although she dont say so...I see she is really disppointed. This dissapointment make me sad and stressed and then I use porn and masturbation to get rid of this stress when she is asleep...the orgasms help me to stay happy.
I think a big problem for me is that she dont need sex as often as i wanted it. Dont get me wrong I dont force her or anything or blame her for this...it is just a fact. My urge raises then and most of the time I released myself.

This leads to a situtaion where I am afraid to sleep with her beacause I dont want to cum to fast and that makes me sad and I start fapping.

Sorry for this long maybe pointless post...but I needed to write my thoughts down to understand the vicious circle I am in.

Well thanks for reading. If you have any questions etc. I look forward to answer them!

Thank you for your help!
