An ex being straighter can make you feel like your penis is the unusual one. Clinically, the useful distinction is not straighter versus curvier. It is stable and functional versus new, painful, or interfering with sex.
Congenital curvature exists on a spectrum
The EAU notes that congenital penile curvature usually becomes apparent around puberty and can point ventrally, laterally, or dorsally. More severe curvature can interfere with intercourse; milder stable curves may require no treatment at all.
Angle can change sensation
A curved penis contacts tissue differently from a straight one. That can make certain positions feel better and others worse. There is no universal “best” curve because partner anatomy and position matter.
Do not try to physically straighten it yourself
Forceful bending, improvised devices, or internet “correction exercises” can injure tissue. If curvature is functionally significant or changing, the right tool is a urologist, not your hands.
New adult-onset curvature, pain with erection, a hard plaque/lump, shortening or hourglass deformity, or a bend that is progressing should be evaluated.
What to do with a partner
Treat the curve as a geometry problem, not a shame problem. Try positions slowly. Let the receiving partner guide depth and angle. If a position hurts, change it. That is normal sexual adaptation for every body shape.
The bottom line
Her ex being straighter tells you nothing about whether your shape works for her. Stable curvature is anatomy. New painful curvature is medicine. Neither is a masculinity contest.
The useful question is “does this work comfortably?” — not “was the last penis straighter?”
Curvature changes which positions make sense
An upward curve may create more pressure against one wall in a face-to-face position; a downward or lateral curve changes that geometry. The solution to discomfort is often mundane: shallower depth, a different hip angle, more arousal and lubrication, or another position.
This is exactly why comparing shapes is less useful than experimenting gently. A “better” curve does not exist independently of the two bodies involved.
Photographing a curve for a doctor is different from photographing it for reassurance
Urologists may use erection photographs to document clinically significant curvature. That is purposeful measurement. Taking dozens of photos from different angles because you are trying to find the one where the curve looks least alarming can become another checking behavior. If you are worried, get a clinical opinion instead of running your own endless photo study.
