i think its better to communicate first and see if the other party is ok with your fetish, because if both don't have consensus, the sexperience won't be nice
not ok: a lady once told me that i am sick for asking her to wear pantyhose during sex. another time, another lady, i was smelling her feet during missionary, she asked me to concentrate on cumming instead...
ok: cummed on ML hosed feet. foreplay/sex with a lady in pantyhose.
90% that i encountered are ok to cater to my fetish
