so this guy (who is turning 19 and I'm 16) I liked a lot awhile ago has recently started hitting me up. He asked me how I've been and we had a friendly conversation. we made plans to hang the next morning because he worked later in the day but he wanted to see me. He was being flirty but I didn't see harm in it. We started to cuddle which led to making out and then we had sex. He then said that he needed to go to work and I had to go soon.. Was he just looking for sex?
