Can you guys please give me some studies regarding the nature of homosexuality?

Hello, guys! Hope you're having a great day! As homosexuality is becoming bigger and bigger in terms of awareness and rights given I am asking whether you could give me some studies regarding homosexuality. Yes, I know that the APA, NLM and others are recognising homosexuality as natural, I am only asking only for the studies! Hope somebody will find the time to give me something to work with, and sorry if you see this kind of posts a lot, haven't seen one and wanted to ask you as I believe you are the most knowledgeable regarding this sort of stuff. Have a good day ^ ^
