I am 38 years old and as of recent, my erections have become less and less. Oddly enough, I usually masturbate a lot but havent been doing it much recently due to boredom, sexual frustration because Im not having sex at all, and simply practicing self restraint. Ive notice that it takes me about a week for my dick to feel alive again. My 4⁴⁴ bloodwork has revealed that i have iron deficiency anemia so Ive been feeling tired a lot more recently. I exercise regularly and try to do cardio twice a week or at least once. Whats going on with me?
