Should I become a eunuch to get rid of annoying sexual desires?

This question was posed in the Reddit Buddhism forum:

Master Ri-Chang mentioned a case from the scriptures that addressed this question:
Taken from his Lamrim Commentary Track 75B:

那个经上面,《四十二章经》上面,你们还记得这段公案吗?有人犯淫,所以他自己想:啊,我这淫心这么大,就把那个生殖器割掉。佛说那有什么用啊!“心为功曹”,那主要的现在这个业的重点在意业,你如果这个地方不修对治的话,不要说那个生殖器,头割掉也没用。所以这里我们要了解,要了解啊!

I read it as your mind is the driver of your actions… not any body organ or external factor.
We are responsible for our mind, thus we are responsible for our actions.
