Get back to sex really working?

I am here to stop PMO to increase the sex with my GF to satisfy her needs.

I am on day 40 and start to think. If I get used to not O will that really help me towards this goal?

I stopped drinking coffe some time ago and I don't feel like going out for a coffe with my friends at al. A cup of tea maybe but coffe ? No

I am starting to be afraid that this might not be the answer to my problem.

Anyone else trying to fix a sexless relationship with NoFap? What's your take on this?
