Indulgence... it usually comes out AFTER I've run it through Ni and feel like its a good idea to "let go" for the big picture, but then i usually get carried away... usually marked by a STRONG desire to do one of the following, and then an intense reaction of pleasure at getting to do it:
shopping (for me & others), decorating, incense & perfume & spraying the house with too much air freshener, eating out, drinking, getting out of the house, rolling around in grass, and sex - majorly -much more Se in sex since being with an ISTP. Also working out, swimming and dancing. Anything physical.
Ni can have an interesting effect on my Se... I think sometimes I can idealize the experience by seeing it as good for me in the long run... so I feel heightened sensation but its also dreamy, like nostalgia during the indulgence.
I also get more into using Se when I'm stressed because I can't put something together in Ni. So if im uncertain of some aspect of the future that makes me feel insecurity, i'll bury my face in the present through Se. Though it can get unhealthy, and I can rebound, judge myself and feel guilty, if I stay there too long.
Oh, and movies... big time.
