Talk to Urologist on Size Increase

hi dear team.

i want to know that, penis size can be increas or decrease .? if yes so what are the reasons specially for decreasing.

when I was 16 my penis was fully straight and 6. + inches near to 6.6 or 6.7. But later some ppl told in fact urged me to masturbate with fake lecture that it's help to release tiredness. I did once in a week. but from 2014 I watched unethical stuff and till 2021. during this period I didn't masturbate but I watched more till the release . so I felt that my penis is not so has moved in curved to the down side and doesn't straight in erection like before. it's erection but with not upper straight like before.

so plz guide me after 3 months i will be married. so I want to reshape my penis like before with previous original size. and I want long time for enjoyment and intercourse.

thanks in advance
