<human>: Summarize the given text in a few sentences.

My little brother and I have been close all of out lives. We've been there for each other through hard times. We can talk about anything, except relationships. 

For a little background, my brother and I are both late bloomers. We both lost over 50 lbs during college, and gained more confidence as a result. I didn't lose my virginity until 23, and I was in a 3 year relationship that recently ended. My brother has made out with a few girls, but only had sex once, and has never had a girlfriend.

Some of my friends think he is gay, some of them think he is a late bloomer like me, but the issue is that I want him to talk to me about it. Every time I bring up my relationship, or my breakup, he gives short one word responses. I've hounded him about details of his love life for years, and I don't get much response. 

I want to be able to talk with him about relationships and love the way we talk about everything else: career, happiness, health, family, etc. I feel like I'm opening up to him about everything, yet there's this huge thing he wont talk about. Maybe he just doesn't think about it, or maybe he has a secret and is afraid. I've often told him that he could talk to me about anything, but with this, I'm lost.

I should also add that I am frustrated because I could really use his advice right now. He's really logical and calm about most things, and my recent breakup has been hard, but he wont say anything to me about it. Contrast this to when I had a tough time finding work, he was full of insight and support. 

If anyone has some advice about getting a man to open up, I would appreciate it greatly.
