Perhaps it will help if you add your PC muscle in the penetration process.

As soon as any girl masturbates to orgasm by any means, she is automatically sexual in my book.

I have always thought if more men could experience anal penetration they would be better at entering a vagina.

Your vagina will gradually change as the muscles are slowly stretched.

There isn't a "spot" in your vagina that will bring you to orgasm. Your clitoral system is complex. It's about clitoral stimulation with vaginal penetration.

I recommend you take control of penetration by practicing with yourself.

If you have not used your vagina during masturbation, then the muscles will be tight.
