I agree - I feel you have some deep insecurities and more importantly, 'misconceptions' about what masculinity entails and perceptions of what makes a person gay. Less masculine straits doesn't equal low sperm count and if you did have a low sperm count, this doesn't mean you weren't meant to be with a woman. If these misconceptions were true, all gay men would be infertile and have less masculine traits. I've seen rippled male body builders who are gay.

If it would make you feel better, go ahead and get a sperm count done - I think you'll be pleasantly surprised. If you are bisexual, that's fine and I understand this might be hard due to your cultural back ground. I suspect you looked at male nudity just to compare yourself. Focus on your self esteem and these intrusive worries you have and everything will fall into place. Good luck.
