Thanks for query,
The shape of penis is due to its musculature.
Anatomically it has tilt on one side due to its blood vessels passing through frenulum
So consider it as a normal.
Sexual act has four stages arousal,erction Ejeculatation & lag period.
Sex is in our mind.when you watch pron film you get all 3 stages of sex together so you have discharge.
So nothing to worry.
