Don't be sorry. It's a legitimately frustrating topic.
On the subject, my husband came from a super fundamentalist family. And his sister came to me for advice, facts and information about sex and masturbation. Since I'm an atheist and sex positive, I gave her factual information. I told her it was okay to have sex, or masturbate, or not. I explained that it's best to start with masturbation because you can figure out what you like, or don't like, and sex has a lot of physical and emotional implications, such as pregnancy, STIs, guilt, etc etc etc. I told her whatever she decided for herself was the best decision and that I'd help her with information if she ever needed. I told her about birth control, hygiene, etc. Her family found out, because she felt so badly about lying by omission and going around her parents (but anytime she tried to talk to her mom, her mom told her she was too young, she was sixteen when this happened, to know about vaginas and masturbation, etc) and so she told her parents about it. So my mother in law told her entire family, extended, that I was a dirty perverted deviant. And one of hub's uncles said I was never allowed their children again.
Fuck that's an awful situation, sorry about that pal. Sex can be a very hush-hush topic in fundamentalist (and migrant) families. A lot of the time the parents believe they are protecting their children by not discussing it but they are invariably doing more harm than good.
