A: While it is a psychological addiction, rather than the physical addictions of drugs, tobacco and alcohol, we've all witnessed people who've tried to stop some form of addictive behavior and failed utterly. And if he's confused about his own sexuality (though my guess is that he is gay, and admitting that would help him get his life in order), that's not helping matters. My advice to you is to stop wondering what is going through his mind, and rather focus on your own life now. Sure, it's natural to want to know why you weren't able to keep him interested sexually, but the problem was his, not yours, and you shouldn't dwell on it any longer, as it's just not productive.

Q: I have noticed that my ejaculation fluid is not entirely liquid, though it mostly is. Sometimes there are gelatinous "crumbs" that come out with the fluid. What exactly causes this? Is it normal? Is this caused by dietary matters? How can I avoid the formation of these jellylike "crumbs"?

A: I'm not a medical doctor, but one potential cause is some sort of infection. Of course, it could be something else that is harmless, but my advice to you is to see a urologist, and don't delay. If you have an infection, the sooner it's treated, the less likely it is that there will be any long-lasting effects. But if you put it off, if there is an infection, it may eventually be too late to prevent lasting damage.

Q: Throughout the years, I have noticed that orgasm can provide temporary relief from sinus congestion. Is this related to adrenaline or other neurotransmitter release?

A: I don't have a clue, though if I had to guess, I would just say that the intense feelings of having an orgasm distracted you but actually had no physical effect. If any other readers can report the same thing to me, however, then maybe there's something to your theory.
