Looking for vaginal bleeding after first intercourse is not a reliable test of whether or not a woman was a virgin. Also, many healthcare providers feel that so-called “virginity examinations” – in which a woman is examined by a doctor prior to first intercourse – place unfair pressures and burdens on women.
Often, men find that if they keep the cut clean, apply an over the counter antibiotic cream and avoid further irritation from partner sex or masturbation, that it will heal on its own within a week or two.
To reduce the risk of vaginal cuts in the future, you may want to use a water-based or silicone-based lubricant, which can help to reduce friction. Also, some women find it more comfortable to “sit” on their partner’s finger so that they can maintain control over the pace and roughness of fingering.
