I want to know how to tell if my girlfriend just had sex in the past 3 hours like from the vagina or anyway to tell. She was at some guys house one night when she was supposed to be at the bar and her whereabouts was unaccounted for between 12am - 2am. At 2:30 am that same day she came back to my place and had sex with me. I want to know from her vagina how I can tell because I remember how it was when I had sex with her right after. Basic question is how is a women's vagina different if she just had sex within the last 3ish hours?
