In Latino culture there is also a big cultural convention against older women with younger men. When I introduced my now husband as the man I was going to live with, my mom threatened to disown me. I stood my ground and told her that I had been a good daughter all my life, and if she wanted to disown me over this, she was free to do so. I told her it was my time to be who I wanted to be and with whom I wanted to be. And that was it. She and I never had any other problems.
I am like you, shy on the inside while appearing extroverted.
I hope you have a great time with your new friend and let things happen.
You know it's love when the pain of being apart is greater than the pain of being together.
