SB 11.14.30
na tathasya bhavet kleso
bandhas canya-prasangatah
yosit-sangad yatha pumso
yatha tat-sangi-sangatah
Translation:
Of all kinds of suffering and bondage arising from various attachments, none is greater than the suffering and bondage arising from attachment to women and intimate contact with those attached to women.
Purport:
One should make a great endeavor to give up intimate contact with women and those fond of women. A learned gentleman will automatically be on guard if placed in intimate contact with lusty women. In the company of lusty men, however, the same man may engage in all kinds of social dealings and thus be contaminated by their polluted mentality. Association with lusty men is often more dangerous than association with women and should be avoided by all means. There are innumerable verses in the Bhagavatam describing the intoxication of material lust. Suffice it to say that a lusty man becomes exactly like a dancing dog and, by the influence of Cupid, loses all gravity, intelligence and direction in life. The Lord warns here that one who surrenders to the illusory form of a woman suffers unbearably in this life and the next.
