Ashamed of penis shape

Since i was young i thought my penis was a weird shape as it curves down when erect, this has made me afraid of what girls will say to eachother after ive had sex with them, i think this may have a big affect on why i have problems getting it up when i need to! Anyone else had similar a problem?

@user_176163 how much of a curve it and what do you mean weird shape. I curve up but not ashamed
