About

        My name is Brian Oestmann, and I am a professional Dominant and alternate sexuality educator in Philadelphia, PA. I am currently based out of Philadelphia, PA where I offer BDSM sessions, classes, and consultations in a private dungeon or a location of choice. I am also available for travel to New York City or Washington DC.

         There are many reasons to visit a professional Dominant: maybe you are "new," and don't really know where to go. Maybe you are busy, and have no time to invest in a power-exchange relationship. Maybe you seek a skilled disciplinarian, who you wish to have a strictly professional relationship with. Or maybe you just want to learn a few skills to take home to a partner.

        I invite any and all who are interested in learning about power exchange and BDSM dynamics to see if you can find something to suit your interests on this website.

        I aim to provide a space that is safe, inclusive, and accepting for all walks of life and all types of people. I work with folk of all genders, sexualities, abilities, and ethnocultural paths.

 

You are welcome here.

About

Sessions AND services

I am available for sessions, classes, couple's advisory, player mediation, and more, as either in-call visits or traveling appointments.

I take in-calls at a discreet and fully equipped location in Center City Philadelphia, ten minutes from City Hall, and close to all major transportation and amenities.
Available setting/rooms can be seen in these accompanying images.

The links below will answer most of your questions, from rules, rates, and interests.

To enquire about public speaking, performance, or large-scale education,
please email Me.
Interests/Limits
To book a session or engagement with Me, 
call 215 301 8701, e-mail brian@phillysir.com, or fill out My booking form below.
  • Though I prefer an email at first, it is preferable to call Me if you are on a time constraint. It is normal for me to take a day to read my emails and two more days to reflect on the matter and respond. Our modern culture of immediacy and the constant fragmentation of time are not very compatible with the kind of life I lead.

  • If calling, do so between the hours of 10 AM and 12 Midnight. Be prepared to answer some basic questions about what you're interested in, how long of a session you seek, and when you were thinking of doing it. I'm quite casual on the phone, and like to get to know you.

  • I can be available most days with four to six hours advance notice. I always prefer at least 24h notice, and reserve the right to deny you your appointment if I feel said notice is not sufficient.

For phone sessions, please check My NiteFlirt lines,
or use My call buttons below!
