I am a 35-year-old man. I smoked five cigarettes a day and occasionally marijuana as well. However, I’ve decided to quit because for the past year, it has started a¬ffecting my erection. I have started doing Kegel exercises and have now quit smoking. Do you think it’ll reverse the e¬ffect? I am also slightly overweight, but otherwise healthy. Can I remedy this situation just with lifestyle choices, without visiting a doctor?
