I just lost my hymen through masturbation. Am i still a virgin?

Technically your still a virgin until a penis enters your vagina as your hymen can rupture many different ways from simple masturbation to riding a bicycle or even just wear away on its own, as for if it will make penetration less painful that would really depend on other things too like how relaxed you are how aroused you are if your wet enough and how gentle he is when inserting his penis.
