If it helps...

Okay so I decided to tell my grandpa because I trust him and he will address this situation without it being spread around the family. I think that if I tell him he can straighten it out, without ruining my aunt's marriage. It was a hard decision to make but everyone is right. And I'm afraid if this goes on any longer I might end up getting raped. I also did some research, I thought sexual abuse is when someone touches you inappropriately or when you don't want them to. Well seeing as I'm a minor, it's considered child abuse for one and asking and pressuring a child for sex (regardless of the outcome) is still considered sexual abuse.

When I looked it up this is what Wikipedia told me:

"Child sexual abuse is a form of child abuse in which an adult or older adolescent abuses a child for sexual stimulation.[1][2] Forms of CSA include asking or pressuring a child to engage in sexual activities (regardless of the outcome), indecent exposure of the genitals to a child, displaying pornography to a child, actual sexual contact against a child, physical contact with the child's genitals, viewing of the child's genitalia without physical contact, or using a child to produce child pornography.

The effects of child sexual abuse include depression, post-traumatic stress disorder, anxiety, propensity to re-victimization in adulthood, and physical injury to the child, among other problems. Sexual abuse by a family member is a form of incest, and can result in more serious and long-term psychological trauma, especially in the case of parental incest."

So there you have it, and thats why I'm going to do something instead of ignore it. Because at first I thought it would go away and now that he's show that it isn't going to go away I need to do something before something happens to me and I'm fucked up for life... more than I already am :\ anyways thank you to those of you that gave me advice! I appreciate it.
