Think Maybe I Am Too Fem And Girly

I love wearing women's panties they are so comfortable and make me feel spectacular when I wear them. I am starting to wear them more and more too to go with other women's clothes primarily sleepwear and pantyhose. Today I was doing the laundry and I realized that I had more panties to wash than boxer shorts, it's literally like my female persona is starting to take over. Then I was talking to one of my best friends and she told me I should start thinking about becoming one of the girls permanently since I am so feminine and am becoming less and less masculine. I started to get worried especially since I am very heterosexual but clearly am feminine. What should I do?
