Hygiene Before a Booking
Clean, fresh and well groomed is the single biggest thing you can do to make a lady enjoy her time with you.
Shower, properly
Shower shortly before the booking, or on arrival if you are visiting her, and pay attention everywhere. Many ladies will suggest a shower together at the start regardless, which is a pleasant way to begin rather than a judgement on you.
Mouth, hands, nails
Brush your teeth, use mouthwash and carry mints, especially if you have had dinner or a few drinks. Keep your nails short and clean; it matters more than most men realise. If you smoke, allow time to freshen up afterwards.
Grooming and clothes
Trimmed is appreciated, shaved is not required. Wear clean clothes that you feel good in, go easy on aftershave, and bring whatever you need for afterwards. Small efforts like these are noticed and repaid.
