SoKlue... my mom was the same and she spent her ENTIRE LIFE miserable. (Not saying that is the case for your mom at all.)
That is the reason why I did and still do - my own thing.
My sister had no issue with giving a dude head though. When I heard this I WAS SHOCKED. The first man I ever gave head to was my exhusband! So now we tease each other about who the biggest ho is! LOL
