i can relate with what you are saying & thank you for saying it.
i believe exchanging fluids during sex is something that happens naturally many times. Other times it is a more conscious act and can be a big turn-on. An ex girlfriend of mine sorta introduced me to that sort of sharing, and she was into that big time! She was very easily arousable and would typically produce a lot of natural lubricant in her pussy. Early on in our relationship, she was not on the pill back then and we were always using condoms for intercourse, she would as part of our "foreplay" often use two of her fingers to probe for her juices and feed them to me. Often she would feed it to herself first, as if to check her flavor, and many times we would share her juices with a deep tongue-kiss. She was always very excited from that kind of sharing and i found that extremely hot too TBH to share one of the products of her lust in that way. Also, as we were using condoms for VP and AP, her mouth and throat was the only way for me to cum inside her. Normally she would just sip it down but also the fact that i had just cummed in her mouth didn't keep us from kissing. So i got a slight taste of
my seed already and for what's hot it felt not different at all to sharing
her juices which we had already been doing.
Later on in our relationship, she went on the pill, and we changed to bareback sex most of the time. In that phase of our relationship it happened more than once that after i had nutted deep inside her vag she would play with our combined lust juices, take them out of her pussy and inside her mouth and kiss me in order to share with me our mingled fluids. It became a regular part of our love-making. Also sometimes i would eat her creampie, our combined lust juices, out of her pussy and share it with her through a deep kiss. There is nothing special to that. It is but a man and a woman enjoying themselves and each other sexually. And i have no clue how that could be seen as something associated with homosexuality. - Truly makes no sense to me.
