Good theories, but that doesn't explain the "Smiles" "bruises" and, most cryptic, "bars in the womb". It may be because spilled semen, such as masturbation, leads to no new life in the womb, hence masturbating creates bars in the womb, perhaps. Or, perhaps the reference is to the fact that if he is incarcerated, then he will never have sex with a woman again, i.e., there are bars in his prison cell that act like "bars" in the "womb" by preventing sexual access to a woman. He is resigned to this fate when he says "I am willing to make love to concrete", that is, his sexual desires will be frustrated by the concrete prison of his cell. "My time as spilt milk" may simply mean no one will miss him or care that he is jailed, i.e., no one cries over spilt milk like himself. "Smiles. Bruises" perhaps refers to a normal prison experience on the surface, but that other prisoners or guards are meting out extra justice to him behind the scenes. What "cruel words sleep above me, mounting and teasing" refers to is obscure at this juncture.
