Someone answered with kindness...
请问你有过性生活吗?这种属于正常现象，不要焦虑。可以自己解决，自我安慰，可以买一些工具。30岁了，人生还没过半，不要自暴自弃。性不是人生重要的一部分，它只是动物繁殖的本能。

Alter your routines so they hold room for the possibility of getting what you want. Actively, with intelligence, learning. In the meanwhile, apply self-satisfaction. Keep it a healthy project so it doesn't backfire. Instinct is not to be directly accepted or denied. It is to be listened seriously. Else we lose our self.
