Will i remain virgin if i self finger
Do not worry about virginity just enjoy yourself.
Remaining a virgin after self-fingering depends on your definition of a virgin.
If you are asking whether your hymen would remain intact, then the answer is that you could possibly rupture it, but not necessarily.
You haven't said exactly how you self-finger, nor how many fingers you use, but often carefully using one finger would be less traumatic to your hymen than two or more.
