So for me I always love being tickled, whenever it is, when it happens during sex usually I am on top and am instructed to place my hands above her shoulders. This leaves my armpits and sides completely exposed and pseudo helpless because if I pull my arms back, I'll fall, what it usually results in is me giggling madly and instinctively pulling back but with my hands still placed so all it results in is the skin on my ribs and armpits being drawn completely taught so the squiggly nails destroy me even more, she probably enjoys the motion it causes down below lmao
Getting turned on *always* makes me like 10x more sensitive so before we start she likes to simultaneously stimulate the fun zone while tickling my feet (one of my worst spots). results in almost these mixied signals where my brain doesn't know what to do so I end up in this manic giggle-moan-giggle-moan pattern and depending whether she puts more focus on my feet or my fun zone it either morphs to hysterical laughter with the occasional moan, or intense moaning/sighing with the occasional giggle. My brain is weird... hehe...
Immediately during and after orgasm I become about 1000x more ticklish (sorry if tmi lmao) so if she is feeling particularly sadistic, she'll set things off and then immediately switch to intense tickling, leaving me in that sort of red faced noiseless laughter that ya get when at maximum tickles lmao
tl;dr? yes and yes and also yes 😛
