Post-addiction sex life. Is it normal to masturbate to get an erection for sex?

I've demonized porn and masturbating to get an orgasm.
Although I am having huge difficulties getting it up to have sex.

The little worry and performance anxiety should go away soon, but i could get a strong erection when I am alone (just a little bit of masturbating), and cant get it up for my girl. The usual rubbing and her touching gets it only half erect or lover.

Is it actually normal and common that a guy masturbates to get an erection to have sex?
Or do you just react normally to the stimulus and so on, and dont have to touch yourself to.

It's sort of that feeling when I have to masturbate to get it up, that she doesnt turn me on or is not sexy enough and I fall back into this selfish habit of self-pleasuring to have sex with a partner or is a normal thing to do before sex?

this feeling and idea stays that: a man should get it up and ready for sex whenever the need for it and not have to wank-start himself to get it up to procreate.

What are your experiences and arguments on this?
Thank you.

 

I have been off from stable relationship 3-5 years now to heal from pmo addiction. And now got a girl and having difficulties, how would you improve your situation to have a normal intimacy and sex without erection problems?

 

Went to my urologist to get hormone and blood check ups. He also got me on a pill to go for a month (similar to V, but better and more specific on erection problems) But I also got my V pill to try out one night and it worked! We talked over about sex with my girl and found my confidence and just tried lots of foreplay with lights on and it finally got hard.

After that my sex life has become normal and I get erections with her at any time.

So I say, V pill with communication, meditation and a will to put in the work and trying out different foreplays worked for me in post addiction stage, when I reintroduced normal intimacy to my life back again.
