Is my husband gay help?

my husband is a coss dresser has been all his life i dont mind it and end of every month i spend the whole weekend with him dressed and have him doing housework and ironing and he can dress on his own on a saturday night okay never had any thoughts he mightbe gay but since the internet most crossdressing sites contain images with cd`s having sex with cd`s or men or when women are involved the women are making cd`s have sex with men...he does look at xdressing porn.porn does not worry me its the fact although he has no interest in gay porn crossdressers are explicit and have male genitails he says the images arouse him as they look like women not men but i cant agree they display erections ,,when hes dressed as a man he has no interest in sissy porn at all ... another thing i cant get round he will mastubate looking at himself in a mirror but i think they all do thatt ...is he so aroused looking ay his own winkie??can other cd`s or wifes off please give their views on this....janice..x
