It's never too late. Some of the ladies like an "innocent" such as yourself.
I'm a 19 year old guy and I've never kissed a girl, let alone held hands or anything romantic at all. How strange is this? Am I too late to start?
Love comes with no timetable so its never too late to start and 19 is really a good age to start here as you bypass all the High School infatuation games and hopefully are getting your feet planted on the ground as to where you want to go. Good things come to those who wait so be patient as someone will appear when you least expect it but also don't jump into anything when the 1st women comes along until youre sure. Also the heart has been known to and really does lie a lot so trust your gut instinct first and then your heart. Good luck
You're still a teenager. There's no need to worry about this. Just enjoy getting to know lots of different girls. When you find the right person for you ... The physical connections you'll have will be natural and comfortable for you both.
There's nothing wrong with you, you're just 19 years old. Movies portray high school kids as always being in some romantic situation or other but the truth is that many teens are college age before they even start to date.
Don't feel pressured to date, sooner or later you'll meet that special person that you'll be glad you waited for.
