Pratimoksha of the Dharmaguptakas 1.28

1.28

「若比丘！婬欲意，於女人前，自歎身言：『大妹！我修梵行，持戒精進，修善法，可持是婬欲法供養我，如是供養第一最。』僧伽婆尸沙。

If a monk, encouraging lustful thoughts, pampering his body, say, in the presence of a woman, “Honourable sister, I am preparing myself by the purest Rule, holding the precepts in their fullest perfection, preparing my self in the law of perfect virtue, which admits of holding these laws of lustful desires, (come) minister to me!” and being thus ministered to by the woman, let him be suspended and undergo the highest penance.
