Thanks for your question. I think your question is somewhat hypothetical. Virgin, as the term refers to a person who has not committed any sexual intercourse. So, you will lose it once you have started doing sexual intercourse with someone. However, there are many stringent and vague rules and concepts regarding to this issue. Some people think that even masturbation can cause losing virginity. This makes virginity a term to be debated on. You have to decide your concept and idea about virginity. In girls, some people refer it to having hymen. Once it is broken, it is said that she has lost virginity. Hymen is a thin layer of skin covering vagina partially. At the first even of sex, it will break of, resulting in the penetration of penis into vagina. This will cause a slight bleeding also. But this need not happen at the first time itself, for everyone. Some women tend to break hymen during activities like sports, dancing, horse riding, bicycling etc. Anyway, it is up to your choice whether to do any sexual activity or not. Fingering may break hymen in some cases. If you are inserting your finger into vagina, it may tear and break. If you are just fingering your vaginal opening and not inserting your finger into it, it will remain intact. Having sex or not is according to your choice. But it is better to avoid unwanted pregnancies, by using contraceptive measures. You can try contraceptive pills, condoms etc. for that. Condoms are recommended for the purpose, as it can reduce the risk of getting contracted with many sexually transmitted diseases like HIV, hepatitis B&C. Fingering can cause pregnancy, if the finger was in touch with penis, which spurted out semen. So avoid getting masturbated by males, after masturbating themselves.
