Is a 20-30 degree curve in your penis normal?

LOL Yes it's normal, 80% of all penises have some kind of curve, some more than others, the most common curve is to the left, then to the right then the upward curve and the downward curve is the least common. It's nothing to worry about, no you can't fix it by changing hands or positions. Remember the human body is not made up of straight parts, a curved penis will fit into another person's body more easily than a straight penis and the curved one will most likely give more pleasure.

I’m 19 as well and my penis when fully erect has a significant curve/bend upwards. I masturbate regularly but never measured the bend of my penis before. I think we are both fine in terms of our sexual abilities even though we’re both virgins. Hope this helps.

nope, it's very common a bending and the more frequent is on the left, expecially for long willy

YES, quite normal.......

Normal, that is not that big of a curve and certainly won't impact your sex life- the penis bends at the base and the vagina is very flexible. If anything it will enhance the sensation for your partner. Forgot to add- not related to masturbation, while many guys have a curve most don't and nearly all guys masturbate.

We all like a gently curved penis.

Most all guys have some degree of bend or curvature to their penis. What you described definitely Falls within the normal range. No worries bro.
