对,是having done
不过你举的例句不太恰当。afraid有两个有些接近的意思:
1) 害怕,结构为be afraid to do / of doing。例如:
I'm afraid to swim / of swimming。我害怕游泳。
2) 恐怕...,用于向对方透露坏消息等。一般用I'm afraid (that) ...的形式。
I'm afraid I wasn't able to finish the task you gave me.
这两个意思一般都不会用到having done的形式。
enjoy后面也是接doing,不会接having done
thank you for后面也是通常接doing,但要强调“已经”的时候,也可用having done,但较少见。与此类似的还有I'm sorry for。
having done最常用的用法是作状语,意为“...之后”,相当于after doing。比如:
Having had dinner, I went for a walk.
应该转化成I used to be happy with playing computer
Afriad of 是短语
Afriad 是形容词
