The speaker describes a life of repeated encounters with different men, and the poem's structure makes that repetition felt. The first stanza lists what changes: curtains, men, bodies. The second lists what stays the same: towels, cigarettes, bed linen, wine. Because the "same" items are ordinary household things, the men start to seem like just another part of the setting, swapped in and out while the routine carries on.
The last two lines shift the tone. "All this lovemaking is so comfortable" sounds casual, even content, but the word "comfortable" is oddly flat for something supposedly intimate. Then the small detail that "They even make me dinner sometimes" reads like a minor perk, almost a surprise. Judging by this, the speaker may be a little numb or detached, and perhaps hiding disappointment behind a shrug. The mood is dry, cool and quietly lonely, with the humour sitting uneasily next to something sadder.
