Lily,
Just a guy's point of view here, but not every guy will be turned off or upset at your lack of sexual experience. As you get to know someone (and allow him to get to know you) he will respect that as being part of you. When that time comes it will feel truly special to both of you.
Being overly analytical and/or hypercritical of others can be a very effective defense mechanism. Focusing on someone's flaws helps keep him at a safe distance but the cost outweighs any benefit.
Don't overanalyze your lack of experience. Sexual intimacy is, by definition, unique to the two people involved. There is no right way--comfort, pleasure, action and response grow from your union. When you meet the right person and the time is right, let it happen naturally.
I will you happiness.
