Hello,
Thank you for writing to us,
Bleeding after sex might be there and not relates that you are virgin or not. so nothing to more worry about it.
As i had gone through your query and you mentioned that you never bleed previously while you had sex. So, i would like to advice you that it might be possibility that this time when you had intercourse pre cum amount should be less than previously you had intercourse. Due to lack of pre cum bleed might be there.
Bleeding may occur if amount of pre cum from vagina is less and due to that penis cant enter in vagina easily and due to that it might possible that you had bleeding issue.
You may use lubricant if it happens each time you had sex so that penis could enter easily. Or you should use different positions in which penis enters easily.
But i would suggest to go for foreplay and
Oral sex first before you go for intercourse because it will help for pre cum and also you and your partner will have more pleasure than normal intercourse.
Still you are facing the same issue than i would like to suggest to concern a good doctor and check for issue they will suggest you better.
Hope you will find it helpful.
Thanks & Regards,
Dr. Gaurav Prajapati
