Mid-twenties female. Never dated before.
Turned down everyone before because the idea of dating never came to mind.
Thinking that I should try out dating now. Any advice?
Dating oftentimes takes up enormous amounts of time, especially if you find someone you really like. You might also find that you don't care as much about anything else if you get smitten.
Don't get physical too fast because it will likely cloud your judgement about the true attributes of the guy you're with. In addition, some jerks will lose interest as soon as they have their "conquest" with you.
Any guy worth having a long term relationship with you will be respectful of whatever pace you're comfortable with so don't rush into physical intimacy. A short kiss should be sufficient to let them know you do like them more than friends.
Good luck! You'll need lots of it because a lot of people will put on their best behavior for the first few dates at least and it may take months to really get to know anyone for who they really are.
All that said, dating can also be really exciting... like a rollercoaster: sometimes scary, sometimes fun, and sometimes makes you want to puke.
