I am in my thirties and have always been into guys. I have never in my life thought about women sexualy. Untill today. My friend of ten years spent the day with me at my house. She is also straight. She was wearing very tight pants. I began watching her butt every time she got up. I did not want to I just could not help it. I felt so wierd but I just kept staring at her behind. I then noticed how beuatiful she really is. She is thin and healthy. I had strong urges to touch her or kiss her all day. I felt so dirty and confused. When she was leaving I hugged her and found my hand wandering down to her bottom. I just had to touch it. She looked at me strangely but did not pull away. I gave her a kiss and it felt wonderful. She thought it was funny and said "your a bit dykey today". I pretended I was kidding around. I am still thinking about her. What the heck is wrong with me? I am scared confused and imbarassed. Am I turning gay at 35 years old? Please explain this to me. I'm ashamed.
