Who I am: Support Pup Cooper

Hi, I'm Dr. Justin Sitron — a sexologist with a PhD, a pup hood, and a purpose.


For over 20 years, I’ve worked at the intersection of education, sexuality, and social justice—helping people better understand themselves, their relationships, and their communities. I bring deep academic expertise, lived experience as a queer kinkster, and a coaching approach rooted in empathy, accountability, and growth.

I’ve helped 1000s of individuals, couples, and communities explore BDSM, pup play, gender, and sexuality with confidence and care. Whether you're navigating your identity, struggling with your body, facing relationship challenges, or ready to deepen your kink practice, I offer the tools and support to help you live more fully—and joyfully—in your authentic self.

Through my 1-on-1 coaching, educational programs, and my subscriber-only Support Pup Community, I create affirming, shame-free spaces where you can explore, learn, connect, and grow. Thanks to Jet Pup Store I was able to launch the JetPacka free-access tier in the Support Pup Community—making it easier than ever for pups and kinksters to connect, learn, and grow together. Once inside, there are paid-subscription spaces where you can level-up your support and participation in spaces specifically about kink/BDSM, sexuality education, relationships, and community leadership.

Looking to level up your journey—or collaborate on a transformative project?

Let’s talk. Book a consultation, join the community, or reach out to work together.

Want to know a little more about my qualifications?

I have undergraduate degrees in Spanish Language and Literature and Education, an MEd and a PhD in human sexuality. I hold certificates in sex education and sex therapy from the Sexological Society of Madrid, Spain. I am bilingual and work in both English and Spanish. I have held leadership roles in some of the premier sexuality research and education organizations in the United States. I've presented at professional conferences, kink and BDSM events, and worked with doctors, nurses, hospitals, therapists, schools, first responders, and other human service professionals, teaching them to incorporate sexuality into their area of practice. I would be delighted to help you or your organization better serve the LGBTQ+, pup, and kink communities in your work.
