You are exuding a confidence and an approachableness and that's attracting the women to you. You are feeling good, and they know it. I love it!
As for too young? 10 years younger is not too young at all. I have been dating men with a bigger age gap since the D and it has to do with where you are in life, not what the number is.
And lets address the texting all the time. It's a strange way we communicate this modern day in age. it is really confusing. We know when we text we can instantly reply. I have a hard time not instantly replying because it's right there in front of me and it's easy to do. But I don't want to be available all the time like that. And yes, there are things that goes through ones head when there isn't a reply. We have to play a guessing game. It's annoying. I kind of miss the day of the phone call. Someone calls, they pick up the phone, have the conversation, and it is over until the next time. ANd it generally happens once a day. With the capability of being in constant contact, that's what is expected these days. ANd it is annoying. I would hesitate to even call it pursing. It's just the way it's done these days.
So, you have options. And you will have more options. Enjoy it all with an open mind and no expectations.
