Abstinence

Abstinence (restraining from sexual intercourse) is the only thing that really makes sense if you are seriously considering it.  If a guy/girl says that to stay with them you need to have sex, well guess what sweetie, they aren't worth it and they don't really love you.  I've been in love, and love and sex are not the same thing untill you married.  Then once you're married the whole thing becomes alot easier to handle and stress free (or as stress free that can be with a new born baby)
