Ideally, for your overall health and erection issues, you should stop all smoking, use of vapor, and daily beers. We've all known about the effects of tobacco, but vapor has problems of its own. Alcohol is too sedating for help with your sex life. Also, if you want to be sexually active with your newfound partner, you should stop all masturbation and use of porn which depletes your sexual energy. If nothing else, do a walking program of at least 20+ minutes per day, whether outside or even just inside from room to room. Eliminate sugary drinks and try to eat wholesome foods of fruits, vegetables, and whole grains. Enough sleep is important. If you've been depressed for some time, hopefully you have been to a doctor. If not, try to get help. Do not push for intercourse right away. Enjoy extended foreplay and oral sex, if you both are agreeable. Twice a week or so, you might allow your girlfriend to give you a slow handjob while you sit back without having to perform. Then, in time, you will become at ease gaining an erection and ejaculating in her presence, also proving to yourself that your "plumbing" is up to speed.
