Pillar · Sexual Health & Intimacy

A real part of health, treated plainly.

Guides on how fitness, blood flow and hormones shape sexual health, written calmly and without shame. Practical, evidence-based, and honest about what exercise can and cannot do.

What actually helps

Quick fixes and supplements
Managing stress and sleep
Healthy blood flow and hormones
Regular movement and fitness

Read it bottom up. The basics do most of the work here. Regular movement, good blood flow and decent sleep matter far more than any quick fix, and the evidence is clear on that.
