"Love him. Love him and let him love you. Do you think anything else under heaven really matters? And how long, at the best, can it last, since you are both men and still have everywhere to go? Only five minutes, I assure you, only five minutes, and most of that, helas! in the dark. And if you think of them as dirty, then they will be dirty – they will be dirty because you will be giving nothing, you will be despising your flesh and his. But you can make your time together anything but dirty, you can give each other something which will make both of you better – forever – if you will not be ashamed, if you will only not play it safe." (1.3.98)
What is the relationship between sex and love presented in the book? Is David's fear that he will find himself sexually attracted to Giovanni or that he will love him? Why, even when one is in love, can sex make one feel ashamed? Why would the shame be particularly strong in David's case?
