How can I get turned on by a woman and have sex with her if I am gay?

Someone from r/sex told me to post it here:I've realised that I am gay and I got some terrifying visions of the future in my head so I want to do everything to not let it happen and have a normal family - wife and children :) I don't want to have sex or be with a man (although it turns me on I would really disappoint MYSELF AND my family)I've also found some therapies, tips and medicine on the Internet - do you know any good ones?
