trans | Hello

Hi my name is Adam and I am straight male. This may sound odd, it does to me when I try to explain it at least. I am physically male and I think I am male most of the time, but I have periods when I feel female. Not that I have done something in a femminine way just that something in my mind has altered slightly and I am definately not male to the extent of being vaguely suprised when I notice my body again. I think these last only for several minutes, but I am not sure because I don't realise they happen until I come out of them.

Has anyone else here experienced something like this? Any advice would really be appreciated.
