That is well said and that would be my reason too... I have had very little experiences that were actually good with sex and relationships, be it sexual or emotional, so I developed strong boundaries that don't allow people "in" (in both ways huehuehue). Now I crave for affection but any attempt by someone to be anything more than friends is seen like a threat. To me it's too dangerous, and I wish I could go beyond these traumas but I'm kinda stuck by the part of me who's in charge of defending me and who got a little paranoid.
