Actually i rubbed my penis on gf skin area and i didn't ejaculate. her outer skin is burning. can she be pregnant by only these reason?

In the scenario you described, pregnancy is not in the cards. It appears that you and your partner are moving in the direction of actual intercourse. It would be wise to learn about appropriate contraception. Here is some information regarding how one becomes pregnant: https://www.plannedparenthood.org/learn/pregnancy

It takes sperm entering a vagina to trigger a pregnancy. If the only sexual activity was like that described, no pregnancy will occur.

No sperms inside vagina- no pregnancy. Use any skin cream on burning area.

While you are not at risk of pregnancy from this episode, your behavior is putting you at risk of pregnancy and STDS.
