Should I message my cousin?

Ive known that I am a faggot for about a year now. Always been submissive and like to please men but findom has its pull on me. Every time I go to send to an alpha, I cant help but think the money would be better in my cousins hands. He is a typical 18/19 yr old gym rat. Hes incredibly sexy and straight. He deserves to be worshipped. I just dont know how to introduce it to him. Should I message him? Should a friend do it? Any advice on what to say or not say?
