Will I lose my virginity by fingering?

Sexual activity (including fingering, oral sex, penetration and masturbation with vibrators) can break the hymen, yes, but so can the insertion of a tampon or even exercising. It's not uncommon for hymens to tear doing totally normal, day-to-day activities, and you can break your hymen without even knowing it.

Now Virginity means different to different individuals, some may consider loosing virginity only means Viginal sex and not Anal or Oral.

For me virginity means any form of sex Oral, Anal or Viginal. I don't consider masturbation as sex hence masturbating will not break your virginity.
