May I suggest some corrections again:
L1 A condom (It needs to be changed throughout the text because it's all around the 'indefinite' condom, though it's not critical)
L3 Let's put me on your dick,->Put me on your dick, (it's said in the imperative mood here)
L9 I am rotten rubber->I am a rotten rubber (a piece of rubber is meant)
L12 Let's quickly put condom on.-> Quickly put condom on. (it's in the imperative mood again)
L15 how do you called me? -dom "I am fucking rubber"?-> how have you called me? -dom "I am a fucking rubber"?
L16 Well, let I will be this, let I will be this,->Albeit I am it; Albeit I am it,
L17 Condom - but I am in in short supply, *->A condom - but I am in short supply, *
L19 I am rotten rubber, let me be so,->Though I am a rotten rubber,
L20 But I save from gonorrhea your penis,->I protect your penis from gonorrhea,
L21 Before you will shove your dick in genital cleft,-> Before you shove your dick into a genital cleft,
L22 Let's quickly put con-, con-, condom on.->Quickly put con-, con-, condom on. (again the imperative mood should be used)
* this is satire of Soviet realities, when there was a deficit of goods
