Vaishnava Samhita. Shri Vyasadasa Charitam I. Vol II Book VI Chp 2 Shloka 10

पौरुषं प्राकृते देहे यावदस्ति हि नश्वरे 

गोपीभाव विहीनानां नाधिकारो लतागृहे 

Those who have the pride of being born males and are attached to their physical forms can not understand Gopi Prem. Such persons do not enjoy the right to serve Shri Radha and Krishna in the nikunja.
