Nikaah & Marriage Issues

Q: Why do people fall in love with the same sex? Can you help someone who desires the same sex?

Q: Recently I have come across the following situation and I am very distressed. Please could you advice me further. My mother was waking me up for the morning prayer and she touched my hand, without any veil in between, and I had a feeling in my private part. However, this feeling was possibly due to fear of erection happening. Also, I had a feeling in my heart when she touched me. However, as it was straight from waking up, I couldn't think properly and my mind just let it be. In the end, there was no obvious erection that occurred. Does this constitute hurmat musahara. Also, what is the meaning of shahwat for this masala. I have read on two respected websites different definitions. One says the occurrence of an erection, whilst the other says an arousing feeling in the private part. Please help me, as this is distressing me a lot, along with the possible implications.

Q: If a man's wife becomes ill and sickly and therefore she will be  unable to satisfy his sexual desires, would it be ethical for a man to get another wife or will it be unethical. The man will still dedicate his time to take care of her needs. He will not desert her. In terms of shariah, does it become compulsory for the man to get another wife if he still has a lot sexual desire in him? If he does not get another wife out of kindness and service to his first will, will this be considered as being foolish while he still has sexual desire and cannot satisfy himself with her?

Q: My question is that I am a homosexual man and I know that it will be very hard for me to fulfil my wife's rights if I ever get married. Is marriage still fard on me  in such a case. I don't practise any homosexual acts but also so know I will never be able to have sex if I got married.
