When rub your virgina aggainst the sofa or something you get this nice feling ?...is this called shagging

No. "Shagging" is slang for actual sexual intercourse.

You've got a couple of errors in your question that are going to cause you confusion down the line. There is no such thing as a "virgina." Here are some related words, though:

virgin = a woman or man who has not had sex

vagina = the hollow tube in a woman's body which leads from outside up to the uterus. The vagina is also called "the birth canal" -- babies come out of the vagina. In heterosexual intercourse, the penis goes in the vagina. Any encyclopedia in your school library will show you a diagram of what's what.

vulva = the sensitive area of a woman's body outside the vagina.

Rubbing your own vulva to get a good feeling is called masturbation.

I'll let you answer it,if you put your hand down(or up) inside your knickers,and you rub your fingers up against your pussy till you got the same feeling,or you got another girl to do the same thing to you,what would you call it?,if you did the same thing,but you put your finger up inside your pussy,it would be called masterbating,yes,but if you got another girl or boy to do the same thing it would be called fingering,so whatever you want to call it,enjoy it.
Let me know what you ended up calling it.

As a very old Englishman in his sixties - this is a good question. In English slang your vaggie is a MUFF. Hence, teenagers say they like to go muff diving!!!!

When I was very young I saw signs that advertised Black Beauty Shag - I thought that was great cus I knew a shag was a bit of fornication outside marriage. Very disappointed when I found out it was a brand of tobacco!

When I grew up (well sort of, and always acted as if I was 13, as I still do) the Americans kindly paid my salary and I worked with many good US men and women.

On trips to USA, my mates always asked where they cud get a FAG (English slang for a cigarette) just to crank up our American allies into fits of laughter.

Later I thought the new Shag carpets were for shaggin' on ... again, sad to find it was the design of the carpet pile.

Now, a plea t'all Americans young and old ... forget the dreadful slang SNOG but definitely stick with the mild and gentle SHAG

Bless you young un's

Yes it is called shagging. Originaly made for shag carpet but u could use ur sofa. Good luck
