I kind of disagree with this take like sexuality does not change the actions taken by both parties. It’s like saying giving $10 to the homeless man on the street isn’t a charitable donation but $10 to UNICEF is. It’s money to a presumably good cause which is in fact charity - and sex (oral or otherwise with a hetero or homosexual partner) is still sex.

For me I base it off of this: if you’re talking to your best friend after the fact, do you refer to it as sex or do you go oh I gave him a blow job, or I fingered then etc. if you wouldn’t naturally use the word sex to describe whatever the act was, I wouldn’t say it’s a body but understand everyone sees it differently

I think any consensual physical contact with reproductive organs should be considered sexual contact and that person labeled as a sexual partner. If it’s possible to transmit an STD in the act, I think it should be considered a sexual act.
