The situations Julie mentioned are common, but I feel the majority of pubertal boys would be horrified by putting on women's clothing and not turned on. And several here started prior to puberty. So I think it may be genetic or earlier experience before we laid down permanent memories (so can't recall them now) that make us enjoy femininity. Julie is new here but seems to be very knowledgeable and self-aware (and very pretty).
Good communication and acceptance are the keys.
