Before I came out, I dated, and was in a serious relationship with a Black Lady. She was more petite than Serena, and a lot more Lady like. Linda was more of a cross between Angela Bassett or Whitney than a Serena. I'm not much into muscles, and Serena's body does nothing for me. Even though I am Gay, I still appreciate and admire the Female form.
If she does marry a JW, it will undoubtedly be a JW who is not fully in. I can't picture an Elder, Ministerial Servant or Pioneer marrying her, only because her spirituality isn't completely up to par as far as JW's are concerned.
