Hi, Welcome To HCM & Thanks For Asking Your Query Here if u are talking about breaking of the hymen and first time bleeding than yes u can lost your virginity even if penis do not go deep inside as there is no such thing like non penetrative sex and even a small penetration can make your hymen to break The hymen is a layer of skin around the opening of the vagina and can be stretched or torn even by fingering and even if your partner insert half of his penis but a lack of hymen is not really a sign of sexual experience. Even a medical expert can’t tell for sure if a girl is a virgin or not In case you are worried about bleeding the first time. Then you should know that one should not even expect every girl to bleed at her first intercourse. Especially if the hymen has already been gently stretched during various activities like sports , horse riding etc I hope it help Thanks again
