I like to encounter weak acid and weakening solution

Weak acid and weakening solution are themselves charged and have their own charm. When they are attracted to each other, they gradually merge to form weak acid and weak salt electricity. Sexuality may be strengthened or weakened

It is like two suitable people falling in love more and more deeply, that is, the electricity between each other is getting stronger

Two inappropriate people are combined with electricity. Sex is still not strong and disappears
