If time is the super-villain of Andrew Marvell’s "To His Coy Mistress," then having sex is the super-power he needs to gain control over his enemy. But, sex isn’t so easy to come by. Possibly because only a very special someone would understand the speaker’s ideas about it. With wit and daring, the speaker discusses sex in frank, beautiful, and disturbing language. Sex is another one of those great mysteries that poets never tire of exploring. Marvell’s contribution perhaps paves the way for more open discussions of sex and sexuality.
The violence in the speaker’s description of his sexual fantasy in the third stanza is directed at time, not at the mistress.
The speaker’s argument that sex will help him control time is meant ironically, and ultimately comments on the fleeting nature of sexual pleasure.
