It would never work between you and me Dao, age difference too big. I liked being with you, now after 7 years your body has woken up, you can look for nice gentle man to look after you.
I am with Jirathip / Som we are close in age and I always like her, and she tell me that she wanted to be with me instead of Suttiporn two years ago.
Good fortune in your future look after your son.
Regarding lovemaking you are perfectly normal in this respect.
