There are various things you can do to maintain spice in your sex
life, but they all boil down to a pair of underlying reasons, and
those're the reasons you need to target with everything you do sexually
if you want to keep things fresh.
They are:
Scarcity, and
Newness
Newness is the "novelty" you mentioned, which is experiencing new
things sexually. That's best achieved by actually doing things
sexually... some of the more common ones are:
Different types of sex (vaginal, oral, anal, mutual masturbation)
Different add-ons to sex (hot water & ice; sex toys; BDSM)
Different positions in sex (an illustrated version of the Kama Sutra here helps)
Different locations for sex (all over the house; hotels; cities;
vacations)
Some of the "kinkier" things (purely subjective, of course) that
more adventurous couples will try are things like:
All those introduce novel elements that keep things new and exciting
and fresh... until you get used to them. Then you need to add something
else.
The other one is scarcity, which you can ratchet up by:
Not living together
Not seeing each other every day
Going on travel without one another
Switching between allowing yourself to have sex raw, and not
permitting yourself to for a while (feels great when you resume and is
quite exciting all over again for a while)
Taking breaks between certain kinds of sex you enjoy (e.g., maybe
you only do anal with her once a month, so it's always pretty special
and exciting for both of you)
Anything that drums up scarcity in certain types of sex or with the
partner herself overall works to make sex more exciting, and make you
want it with each other more.
Long-Term Novelty
