Sex is the foundation of our society, all of us got here because of sex. Marriage exists because of Sex. Not to sound like a nymphomaniac, i'm just stating the importance of sex in our society and all society, really. People don't understand just how important sex is in our society and culture. I hate to say the truth that many want to ignore, but Sex for women is a way of advancement financially and financial stability, even for men these days. It is easy to dismiss Sex now but you don't know if you'll want children 5-10 years from now. Your ability to get a sexual partner(husband, GF, wife, etc.) could effect your long-term happiness. Plus it's easy to understimate how society will view someone who is basically a eunuch. Most will make assumptions and most know from peer pressure in High school that society expects people to be sexually active. Lack of perceived sexual activity can result in judgements regarding your manhood(or alternatively, judgements about your personality if you're a female). It's sad, but reality dictates that if you're capable of sex you're more likely to succeed in society and be happy.
