no more (and probably less) than any trace hormones that may be in bodily fluids in a heterosexual relationship. those minute traces will not result in any harm or cause side effects in a partner.
when female is taking testosterone (inject) 2 bcom male do the fluids shared by her female partner contain testosterone. if there is a small level of testosterone in the fluids (saliva etc) can it have an effect on her female partner such as anxiety and all the others that can occur with the injectee but maybe to a smaller degree.
