He was a womanizer, at college or outside (at club, etc). He always so careful, didn't wanna get any girls pregnant, of course

This week, every night, he just stayed at apartment and 'did' you all night after you two finished your college homeworks. And you didn't know why he like that, usually he brought random girl or stayed outside and back in the morning. Maybe he quit being womanizer?

"How's it?" he asked as leaning his back on ur door frame, waiting for you to finish your homework
