Troubled by Homosexuality

Dear Dhananjay,

I am 20 yo, and recently found out about Brahmacharya after a porn addiction that lasted from 12-20. In this time I lost a lot of vital energy. I was never sexually attracted to men growing up but my addiction caused me to distance myself from women and now many think that I am in fact homosexual. I have always wanted to grow up and have a wife and kids, but the pressure to be gay is getting to me. Homosexuality seems unnatural but these days people feel that one is pretty much born that way. I also don't feel as manly as the men around me so I'm wondering how I can regain my masculine energy through brahmacharya. At the moment I feel physically, mentally, and emotionally weak, especially since I broke my practice last night after 2 weeks. Not eating meat these past few weeks has also made me lose weight and thus made me feel weaker. Homosexuality is also frowned upon in my native culture although I'm now in America. I really do no wish to be gay, but do I have a choice? What must I do to purify my mind and heart? And how should I deal with those that insistent that I am gay?Thank you in advance.
