sex and such

So last night I was wondering if people without trauma in there history can have issues with sex and touching and being with someone?

Because I can swear up and down that nothing happened growing up you know, no one can prove anything happened and so if i dont say anything or tell anything then its like im 'normal' i guess. but i have major problems with having people to close to me, like just standing and talking. i hate being touched, and i never ever see sex happening in any form or fashion. i dont even like anyone being in the same bed with me .. there are exceptions to that one cas obviously the kids i babysit and i have shared a bed with like siblings and friends every so often, of course nothing involving sex or anything ever went on..its like well sleeping. and it makes me think that im just a walking contradiction i guess. i can say nothing happened. but everything just kinda screams that something did happen.. i cant pretend that i want a relationship..because in general i really dont know if i do or not..or who i like or not..i like being able to keep people romantically away from me because then that is just something i dont have to worry about..you know..i dont have to worry about being expected to do something i really dont want to do..

but if i had grown up with nothing having happened would i still be struggling with the same issues ? would i have learned differently and been ok with being touched and all that?
