Wonderful night celebrating International Womens Day with @wearfigs.
If only I could glambot.... 😂

Size is one of the most common questions men ask, but when you actually ask women, the answers are often surprising. Many say size isn’t nearly as important as people think, and comfort and connection matter much more.

Some performers say being very large can actually make intimacy more difficult.

Porn was never meant to be sex education, it’s entertainment.

Behind the scenes, filming often involves long hours, uncomfortable conditions, and a lot of staging that viewers never see. The reality is far more complex than most people think.

Should you get every medical imaging test just because you can? 🧠

With endless options and more access than ever, Dr. Matthew Davenport breaks down why sometimes more information isn’t better—and how over-testing could actually put you at risk.

Stop it right now! 🛑😂

Don’t tell the Silicon Valley 'Optimization' bros, but @alanchikinchow and I found the ultimate biohack. 🤫 It’s called 'consistency.' Who knew 8 hours of sleep and moving your body actually worked? 🐱🩺 Thanks @dhar.mann & @dharmannstudios for organizing a great creator event.

Worried your gym form isn’t perfect? Research shows weightlifting causes just 2–4 injuries per 1,000 hours—close to walking, and far lower than contact sports. Most injuries resolve within two weeks. Don’t let fear of “perfect form” stop you from strength training.

BPC 157 sounds promising for tendon and ligament healing—but there are zero randomized clinical trials in humans. Most data comes from petri dishes and rodent studies. Before trying it, know what the evidence actually shows (and doesn’t). Talk to your doctor first.

Peptides are often abandoned pharma projects that failed trials — now marketed as miracle fixes for joints, gut, and brain. They’re not supplements and aren’t regulated. If one injection claims to solve everything, pause. In medicine, true panaceas are rare. If it sounds too good, it usually is.

Does technology really reduce our desire for real relationships—or just change our habits? Dr. Kenneth Hanson shares how sex tech users often keep the same (or more!) desire for real partners, while lowering unhealthy behaviors.

Creatine is well researched—but not for testosterone. Of 13 studies, only 3 showed small, inconsistent increases; most found no effect. It’s great for strength and muscle growth, not boosting T. For healthy testosterone, focus on sleep, lifting, stress control, healthy body fat, and proper nutrition

PRP injections may offer longer relief than you expect—often ~80% symptom improvement for a year or more. Platelets release growth factors that reduce inflammation and may recruit stem cells to support healing. For chronic joint pain, it could be worth discussing with your doctor.

Struggling to tell your partner what you actually want?
Most of us got terrible intimate health education.
That's exactly why I created my Better Sex app. It's the comprehensive education you deserved but never received. Check it out at https://www.studio.com/rena for less than $1/day

Walking loads bones ~1.5x bodyweight. Running? ~2.5x. But bone-building osteoblasts need 3.5–4x bodyweight. That’s where jumping comes in. Try 10 minutes of multidirectional jumps 3x/week—or 50 jumps a day in sets. Small impact, big difference for bone density.

70% of hip fractures happen in women. After a break, there’s a 30% risk of death within a year—not from the bone, but from complications like clots and pneumonia. Many never return home. Bone health isn’t just calcium. It’s strength, balance, and independence.

Your muscles without bones? Just a pile of tissue with nowhere to go. Bones give us structure, strength, and the ability to move through life. But here's what most people get wrong: joint pain isn't an inevitable part of aging. It's common, yes, but not a guarantee.

Perimenopause and puberty in the same house?

Are you stuck feeling like you're "failing" in the bedroom?

On this episode, Dr. Charmaine Borg reveals how shifting from judgment to curiosity and play can help overcome anxiety and self-disgust when facing issues like erectile dysfunction or premature ejaculation.

The average ejaculate volume is 1.5 to 5 milliliters, with most people landing around 3.4 milliliters. That's roughly two-thirds of a teaspoon. Lower volumes can happen with frequent intimacy, dehydration, or certain medications. Higher volumes don't necessarily mean better fertility or function.
