Feminine guy means feminine friends

...Sarah McMillan. "Hey Jon!" she grinned "I'm here for our study session." "Huh?" I asked confused by both her friendliness and the fact that she was here to study. "Gawd you fembois can be such ditzes sometimes," joked with a wink. She stepped past me and closed the door. "Remember we agreed after first period that we'd have a 'study session' today so you could help me pick out new clothes for my date with Biff." "Err," I replied confused, but she didn't seem to notice. "I don't know how you guys do it," she smiled, sitting at my computer. "Do what?" I asked, sitting on my bed delicately. "You fembois just know what guys like **and** what looks good on a girl," she replied, rolling her eyes. Unlike the Sarah I knew who would roll her eyes contemptuously, this was affectionate, friendly eye rolling. I just smiled and nodded, blushing slightly at the compliment. "Where do you want to begin," I asked looking forward to a spot of internet clothes shopping.
