Being a virgin in this generation

I figure I will not be the only one who feels this way, or maybe I will. I am a 21 year old college student and I am 100% focused on my career/dream job. I love what I do and I have an extremely fun social life, but I am still a virgin. Not only that, I have never experienced a real relationship or level of intimacy with anyone. The only times I have had intimate experiences (every but sex) has been when I'm super drunk. I know I don't live in a romance-comedy, but I just feel like sex is a major part of the human experience and it's something I feel left out of. Hardly anyone I know is a virgin, and especially in this hook-up culture we live in today, I just don't know where 21 year old virgins fit in. Whenever I'm attracted to someone, being a virgin feels like a burden I wouldn't want someone to deal with. It sucks. I am generally a confident, optimistic person, but this is something that I think about everyday, and it really lowers my self esteem. How should I deal with this? Am I alone? Also if I meet someone and we hit it off, what is that conversation going to be like when I tell him I'm a virgin? I guess what I'm saying is that I'm scared. Does anybody have advice or feel the same way I do?
