Sex is difficult; yes. But those tasks that have been entrusted to us are difficult; almost everything serious is difficult; and everything is serious. If you just recognize this and manage, out of yourself, out of your own talent and nature, out of your own experience and childhood and strength, to achieve a wholly individual relation to sex (one that is not influenced by convention and custom), then you will no longer have to be afraid of losing yourself and becoming unworthy of your dearest possession.
