Got a question, is it cheating when you have sex with a girl you've only known for a week but you've been steadily having sex, going on dates, spending weekends together with another girl for the past 5 months? Like if you technically didnt ask the girl out 5 months ago and you guys just started having sex again and hanging out on weekends.... you're not really dating, right? Take into consideration that the 5 month girl is actually your ex from highschool (whos cherry you popped) and part of college and you two have known each other and have been really good friends for the last 12 years and both of you have met each of your past serious significant others. But, also consider the fact that the girl you've known for a week is quite possibly the hottest female you've ever talked to face to face and is only 18 years old/dumb as a brick.
