Help docs! I'm wondering if is normal for a man not to have sexual pleasure after a bad break up?

Yes. You'll lose interest for a while. That's normal. You're going to learn from this experience -- this was the wrong person for you anyway, and you'll gain skills taht will be better when the right one shows up. You're tough and resilient, just because you're a man. If you're not getting pleasurable morning erections in a month, talk with your physician (health checkup) and a counselor. Best wishes.
