I can not understand the meaning, please help

I have read a post about IC muscle but I can not understand a point that thread starter indicated.

Kegel - the secret revealed

“Corpus Cavernous builds upper 80-85% of penis. You have to look at some anatomy drawings to see where crus of penis is located. This is Your starting point. This is also where IC attaches. Now try to apply gentle, internal pressure forward towards the glans of penis but keeping in mind that You are interested only on the upper part of it. You will eventually feel it. It’s about 1-1,5 cm behind the pubis.

And One VERY IMPORTANT thing I would like to add here. About TUG-BACK. DON’T TRY “escaping” with your penis to the inner structures of Your pelvis. It’s the worst You can do because it kills Your erection. If you perform this little pushing forward, You will feel gentle moves where penis enters the body, in front and a bit under from the pubis. Movement of 1-3mm.”

What did he mean with second phase. DON’T TRY “escaping” with your penis to the inner structures of Your pelvis. What does it mean?

Thank you.
