i don't think being a virgin or not being a virgin is anything to be embarrassed about personally, or proud of. who a person is, is so much more than what their v-card status is.
I know in this day and age its considered strange to reach a certain age and to still be a virgin. but really who cares? some people might make fun of virgins, but to me that reflects more on the people making the jokes than on the virgins. I think its actually kind of sad to only be able to view sex as such a light topic to the point that you think everyone should be doing it.
as for non-virgins, in Christ all sins are washed away. People may still look down their noses at non-virgins, but thankfully what they think doesn't matter. what God thinks does, so long as we aim to live our lives for Him, thats the important thing.
so yeah... i'm not really worried about someone else's virginity or lack thereof. None of my business anyhow.
