I am an 18 yrs old female. I want to have a real relationship, but everytime i get the chance the same thing happens. We hang out for a bit, every thing is great we get to know each other and all that gooey mushy stuff, then as soon as we have sex I lose interest in the guy. and its not like the sex is horrible i mean there was one or two times but most of the time its f-ing great. regardless i lose interest and then i want nothing to do with the guy. sometimes we try and be friends but it just becomes awkward. whats wrong with me?? i try to have feelings but they are none exsitent, why is tht? i am not a promiscous person at all, I havent had sex in forever because of this (6 months and counting).Its hard for me to actually express my feelings. My ex told me i was a robot cold and emotionless. i would just like some opinions on this whole situation. I discussed this with some close friends and they tld me i should see a therapist because i might be a psychopath.
