I’ve not had sex for 4 years and counting, just masturbating. Fast forward to a month ago when I had a quick link and when it’s time to penetrate I became placid instantly. I couldn’t control how embarrassed I was. By the way I’m 24. What can I do. I think I have a weak erection now.

Try getting herbs or go for medical check up
Stop masturbation. They may say it is not medically harmful, but in reality, it kills your sex drive, it is addictive and makes your erection weak. Spiritually, it makes you loose focus and very weak spiritually too. Stop masturbation now and try to each well and exercise regularly!
Probably you have a spiritual wife.
Seek for spiritual help before it destroys you.
