Well I am glad you have met someone sweetie hugs!
Sounds like he has done a little research there himself...you may be surprised.
I shall hope and pray that you find the courage of will to open and honestly communicate with him the way you have just done with us sooner rather than later my sister.
Ive tried keeping things vanila before and not mentioning anything directly in other relationships and had some limited success in some ways...but nothing beats having it all out in the open ,,the naked truth if you please if the only thing that can really set you free.
