If you are taking about breaking your hymen through abortion, that's an arbitrary measure of virginity. Hymens break on their own, from tampons, gynecological exams, etc.
Many people would consider getting pregnant the way you did to be a loss of virginity. Virginity is a state of mind, not just if you've ever had a penis in your vagina. You are still exposing yourself to all the STDs and pregnancy (obviously). You are still experiencing the emotions that go with sex.
Are you having the abortion because you want to or because you want to preserve your virginity? The second would really be for the wrong reason. Really think about why you are so set on preserving your virginity and ask yourself if having an abortion is consistent with your values. If you do it for the wrong reasons, you may regret it for the rest of your life. Just be sure.
