Most Helpful Girl
Take it from me girl: the less men a woman has in her life romantically, the better off she'll be in the long run. I learned this the smart way, not the hard way like so many others.
When you lack romantic experience, it can be easy to romanticize and glamourize dating and relationship. However, the truth is that most men do not know how to take care of a woman's heart. Most guys, especially guys who are new to adulthood, are potentially going to taint your journey with their immaturity and bullsh*t. This is why you shouldn't feel bad if things don't work out because a truly special man and bond is rare to find and once it's found, it takes on a life of it's own. Women tend to be emotionally, mentally, spiritually healthier when they are highly selective about their male experiences so don't feel bad about being your age and single. It's not a weakness: it's a HUGE STRENGTH.
Anyhow, it seems to be that you are just very shy, self-conscious, and timid. The cure to this is pushing yourself out of your comfort zone and doing things that scare you no less than three times a day. Embrace fearlessness and those butterflies will be long gone! Good luck!
