Does Tucking the Penis to the Side in Underwear Cause Curvature?

BY DR. PAULO EGYDIO · CRM-SP 67.482 · RQE 19514

The position of the penis in underwear can affect men’s sexual health — how to position your penis in underwear.

How to position your penis in underwear? Every man should know this answer. Both the type of underwear and the moment and way you tuck the organ can influence comfort and even health. This question came from a reader, who also asked whether there is a risk of developing penile curvature when placing the penis inside underwear. Check the tips below to avoid problems.

Does tucking the penis to the side in underwear cause Peyronie’s disease?

The penis position inside underwear does not by itself promote fibrosis formation that leads to penile curvature. Simply tucking the penis to the side in underwear — as long as it is completely flaccid and without forcing it — will not make the penis crooked. Peyronie’s disease arises from trauma and micro-traumas to penile structures, which trigger scar tissue (penile fibrosis). These injuries happen in situations that force the erect penis. The risk lies in keeping the penis to the side while you have an erection (especially with tight clothing) or in forcibly pushing an erect penis sideways. Such situations can indeed bend the penis inside the underwear.

How to position your penis in underwear

There is no single “correct” position to tuck the organ inside underwear. Pointing the penis up or down, or to either side, is a personal choice. The best position is the one that feels most comfortable for you. When you tuck the penis, it must be completely flaccid. If it is erect, there is a risk of trauma that can lead to fibrotic plaques and Peyronie’s disease. In situations where an erection is likely — for example, on a romantic night — it’s best to avoid keeping the penis to the side inside underwear. With an erection, a micro-trauma may occur.

Comfort tips for wearing underwear

Choosing underwear also matters for penile health. Prefer natural fabrics, such as cotton, which allow the skin to breathe and help prevent fungal infections. As for style, any model can work as long as you avoid tight underwear. Simply wear the correct size for your body. For men with a penile prosthesis, boxer models are ideal, as they help conceal the implant and avoid embarrassment.

Other care your penis deserves

The penis requires ongoing attention: hygiene, maintenance, and prevention. Here’s what men should do to take good care of the organ:
  • Hygiene in the shower: wash the penis properly. If uncircumcised, retract and clean the glans. Dry well after bathing.
  • Clean hands: always wash your hands before touching the penis to avoid infections caused by microorganisms.
  • Medical checkups: visit a urologist. Besides guidance on Peyronie’s disease, the physician can detect issues such as prostate or penile cancer.

Book a consultation to discuss penile curvature and positioning in underwear
