attracted

Q: What is the Islamic stance about a (Muslim) man who has sexual attraction towards men & not towards women? He has tried everything - consultation from authentic scholars spiritual healers & psychotherapists, prayers & invocations, & even marriage, but all in vain. What should he do? What should he believe about himself? Is he a sinner? Will he be sent to hell?

Q: Is it permissible to reject a marriage proposal on the grounds of not being physically attracted to the person? Or does attraction only come after marriage?
