My therapist says all this violence may have led to my using women for sex and never getting attached. Yes it could. This means they do things to the outside world. Though this is a generalization and doesn't apply to everyone, it often does. For them, sexual acting out takes the form of sexual addiction or a sexual style of using people without ever becoming attached.
Women act out sexually, too, but the pattern is more common in men.
Sexual consequences of growing up in violent homes are not as widely studied as other effects such as depression. Much suffering, both sexual and nonsexual, occurs. It's great that you're getting some help. When I was growing up, I was taken advantage of by boy after boy. I believed it when they told me that I had to satisfy them after I got them excited, and that if I cared about them I wouldn't let them suffer by not finishing the act.
