I don't think it matters! Everyone is an adult, and this should be acceptable to everyone. As long as both sides have a sense of responsibility and pay attention to protective measures, sex is the best way to express love! We should learn to enjoy it instead of indulging in it. I am an adult, and many of my roommates have got rid of virgins. I'm gay, I'm currently in love, and I haven't had sex, but many of them are taught by our teachers.
