Subs often ask Me if there is anything in particular they should do to prepare for a session.  Usually their mind is wrapped around their genitals and thoughts of edging, looking at photos, etc. are in the forefront, but there is a practical side to preparing for sessions too.  Subs get excited and sometimes forget the common sense practicalities of preparation.  Below are some pointers for making sure your session goes well.

• Hydrate well prior to your session.  When things go wrong physically in a session (lightheadedness, nausea, tiredness, etc.) it is usually from dehydration.  This is the number one cause of fainting in session.  If you are having a particularly heavy session or a session that lasts 90 minutes or more, take a bottle of water or a sports drink with you in session and don’t be shy to ask for a swallow.
• Eat normally.  I know pre-session jitters can lead to an adrenaline rush that can cause you to lose your appetite prior to a session but failing to eat can cause the same nasty issues listed above.  Even if you aren’t hungry try to at least eat a light meal prior to your session.  Low blood sugar due to a lack of food can really be a buzz kill in session.
• Practice proper hygiene.  This should go without saying but be sure you arrive clean and fresh.  If you are coming from work or a flight and feel sweaty, ask to take a quick shower.  If you are odiferous your Domme won’t want to get too close.  If you will be engaging in anal play, give yourself an enema approximately 2 hours prior if at all possible.  I know this will be TMI for some, but all subs should clean in that area by inserting a soapy finger in the shower until it comes back clean.  There is nothing worse than spanking a sub and when you turn him over your knee he smells like ass.  Take this advice.  Your Mistress will appreciate it.
• No cologne, please.  I know you think your cologne smells sexy and manly – and it may, but it’s not appropriate to wear it in session. Particularly strong scents have given Me a headache or caused Me to sneeze.   There is also the issue of transference.  Strong scents can transfer on to Us and We end up smelling like you.  A busy Domme can go home smelling like a department store fragrance counter.  I don’t wear any perfume in session for these exact reasons.  Please reciprocate.
• Manscape if possible.  I know this is not an option for everyone, but even trimming can be a help.  Having to navigate around a full bush of hair to perform CBT can be awkward and actually hurt you in a not so good way.  Trim the shrubbery if you can.

In addition to these points, follow any specific instructions your Mistress has, including being chaste, preforming edging exercises or whatever She desires.  We want to have a good time just like you do, so do yourself a favor and prepare accordingly.
