It is sexism to make it out to be a "he said she said" situation when a man says it was okay for him to kiss a woman and she says it was something she did not want. You disregard her personal autonomy when you say that him claiming she wanted it is as valid as her stating she did not.
If I hit you in the face with my fist claiming you wanted it, should I get off the hook since as you deem "no one can tell whether you wanted me to do it or not"?
For anyone wondering the "soccer incident" refers to his bad take on Luis Rubiales kissing Jenni Hermoso without permission.
EDIT: Fix a typo
There is about 8.1 billion people in the world. Assuming romantic cliches to be true and that we all have exactly one soulmate out there, we would have a very hard time sifting them out. If you were to use exactly one second at meeting a person it would take you 257 years to meet everyone alive on earth at this moment, which due to human life span being significantly shorter and the influx of new people makes the task essentially impossible without a spoonful of luck. Moral of the story: If you believe you have found your soul mate, be extra kind to them today.
