Unexplained Urge To Be With A Man

In my early twenties I became friends with another girl in my age group. After a night out with friends she suggested that I stay with her and not drive to my apartment. Around two in the morning she came and got me to come to bed with her and get off the couch.

Over the next week she kidded me that I had 'slept' with her. At the end if the week she asked me to spend the weekend with her, she reminded me how warm her bed was. The long story short is I spent the weekend in her warm bed and she gently showed me how much she liked me.

Over the next while we dated, spent weekends together, experimented. We have live together for four years. Then one day a guy pulled me to him and I went home with him. I can't explain why I went with him. I like living with her, spending my free time with her, sleeping with her and getting close, but he makes me 'want it'.
