The best ways to "cover all the bases" with a new romantic partner are:
First
base (i.e., hugging, holding hands, foot/back-rubs, etc.): Taking deeply-cleansing showers beforehand, brushing teeth, trimming hair and nails, etc.
Second
base (i.e., kissing, close snuggling, sharing non-intimate full-body massages while wearing just a bathing suit or undies, etc.): Taking all steps described in "first
base", plus using breath-fresheners, antiperspirants, soothing and/or aromatic oils, etc.
Third
base (i.e., French kissing, naked cuddling, intimate massages, sleeping together, etc.): Taking all steps described in "first
base" and "second
base", plus having easy access to a warm/cold shower at all times, keeping the bedroom a comfy temperature, etc.
Fourth base (i.e., handjobs/blowjobs, "going all the way", etc.): Taking all steps described in first three "bases", plus having plenty of condoms and/or personal lubricant handy, keeping tissues and damp wash-cloths within
easy reach to clean up "
messy" aftermaths, having changes of sheets and pillowcases to put on the
bed if necessary, etc.
