With the teaching part, just take it slow. Start with the basics and get more advanced with the subject over time. With trying to get her to let you touch her breasts and vagina, you shouldn't even try. SHE IS YOUR SISTER! That is the most perverted thing I have ever heard of. Good for her not letting you touch her.
no
Yes, if the parents of the child (your sister and the father) allow it.
The clubs normally allow you to touch the girls if they put their hands on your hands and move them to their body.
That depends on the virgin herself and the relationship between her and her boyfriend. If they are open-minded and on open relationship and are not too religious, then maybe. But young people are usually very idealistic. If the virgin has made up her mind she does not have sex before her marriage, it is very unlikely she would allow touching her at all.
It is the vagina.
Because men's bodies were not designed to deliver babies. The vagina becomes flexible enough to allow a baby to pass through. Also, the vagina is designed to accept the penis during intercourse.
He/she probably does not want you touching his paws and they maybe hurt...
Generally, the laws of the Western World allow such marriages.
no
they like to "play" the vagina, of course, but to get a man to have a boner they would like breasts more. To seduce the man allow him to lick and suck your breasts and finger your vagina and suck his penis to lead to sex.
No where in Star Trek does anyone say that Vulcans kiss with their fingers; touching with two fingers is the most contact they will allow themselves to have in public.
It'll rot inside you and make you sick.
