[tlover]

If hes still not responding to you and as you have tried talking to him about it and indulging him i don't think there is much more you can do just now.
Perhaps he needs more time, mabey his interest in shemales has become a bit of an obsession and hes trying to get his head around it just as much as you are.

I know with my gf there was a period when became a bit obsessed with tgirls and was myself wanking off a lot to it and i neglected her a bit, but we where also going through a bit of a lull in the bedroom anyway, now things have returned to normal.
I have come to realize my obsession is now a bit like a hobby a pastime not a life choice, just another part of my sexuality.
I know one thing for sure, I'm very glad she doesnt know about it, i think it would cause just as much upset as you are feeling now.
Maybe your boyfriend is very upset you know about it and you bringing it up.

I think you need to cool down about it and give things time before you have ago at him again.
He is probably confused and you are felling rejected i think you both need time to think things through.

Just my humble opinion, mabey someone else has got some ideas on your problem.
