It's hard to understand your question; if you use a street slang term for parts of the body, the software will often block it. If you use the anatomical name for a body part (such as penis or vagina) it should come through. If the words had come through, would your title have been "Is rubbing vagina with penis and not to insert in vagina is chances of pregnancy"? If that is what you are asking, yes, there is some chance of pregnancy. He should not be rubbing his uncovered penis on your vagina if you would not like to accidentally get pregnant. You should be using condoms and it would be a good idea to also be on the pill. It is not the easiest way to get pregnant, but it is possible.
Hi - If you let us know what you meant - and I'm guessing you meant rubbing your vagina with his penis - we can edit the title of your post.
If your boyfriend is not inserting his penis into your vagina, you aren't going to get pregnant. But that is REALLY close to sex so I'd get some condoms to be safe! Good luck
