personally, I was the exact same way. I was attracted to my second cousin from the second we first reconnected. He always acted as though he was attracted to me as well. But, when I found out we were cousins I completely shut the idea out of my head. I was scared. I was scared of what people would say. Scared of losing friends. Scared of how the family would react. It took me getting in a relationship, and getting engaged to that abusive piece of trash to finally came around. Charles gave me the courage to leave. He was always there for me. It took that expierence for my sister to come to me and (although he had told me) tell me that genetic wise we would be fine and that I shouldn’t care what people think and say. It took her telling me that it wasn’t illegal in our state. It took seeing that no matter what, he was always going to be there for me. I don’t know if you’ve tried it yet or not but try going about it at the way of just showing her, it’s okay. Now, Charles and I have now been together for 9 months, he has started talking about the future... but... the only people who know we are together is my mother, sister, brother in law, niece and nephew, and a few of our friends. We have yet to take the leap and become public (his wanting... I want to scream it from the rooftop)
hope i helped.
