This is an interesting topic to me because I want to do research on human sexuality after I'm done with school. Coincidentally, I'm reading about child sexual development right now, and how a repressive upbringing can cause serious issues for an adults sexual development and relationships. It can result in serious trust issues and even make the child more vulnerable to abuse. This continues into adulthood, with the individual seeking out abusive relationships because they see that as the norm.
As for myself, I was raised in a very religious family who held very firm and unrealistic beliefs about what was appropriate and inappropriate sexual activity. I was taught that anything aside from kissing was wrong before marriage. Because of this I was left very uninformed when I was trying to figure things out during my adolescence. I didnt have anyone to turn to or ask questions of because I knew that I would be judged harshly as an immoral sinner. As a result I was in an abusive relationship and was easily taken advantage of. I still have serious trust and body image issues, which have a very detrimental effect on my current relationship.
