Why did I wear my girlfriends clothes?

dalereimers
a few weeks ago my girlfriend went with a friend on a shopping trip fow 5 or 6 hours and while she was gone i wore her clothes. I wore her skimpy clothes like her crop tops and tight shorts and her swimmer one piece and bikinis amongst other things, then i edited photos of myself to have a girls face and i put the photos of me in her clothes and of me looking like a girl in a secure folder that she couldn't get to but i screwed up and she found out and she was really angry and I'm ashamed of myself, why did i want to wear her clothes, i had problems like this years ago when we were first getting together i thought they were buried deep in the past but those burning desires lead me to be dishonest and sneaky i don't know why i couldn't tell her. I'm straight too i don't like men. My girlfriend has aksed me not to string her along this ride with me because she doesn't want to date a man who wants to wear her clothes i don't feel like i want to wear them again ot be a women but I'm worried those feeling will resurface what should i do and please don't be mean to my girlfriend she has tried to be patient and supportive i shouldn't have lied to her but she's dealing with this as best as she can and trying to help me too, what should i do? Why do i keep feeling like this, is it normal to have these phases?

Please keep all your opinions about my girlfriend to yourself she very much loves me for who i am i don't think she deserves to be condemned because she just isn't into a feminine man, she has not asked me to change or given me a cruel ultimatum, she has said several times she wants me to be who i am but she also personally herself just can not be turned on by it she wants me to find someone who is attracted to someone who is a feminine man, please understand this and leave her alone
