One of my favorite things to do at weddings is play “Spot the Slut”. Basically me and my wife try to find the one person who came not to celebrate the wedding, but land a hookup. Short dress, low cut vibes, drunk. What have you seen that would make you say, “Found the Slut!”?
Humorless
The word you’re looking for is Humorless.
As in, you’re being an uptight humorless person and none of that is happening. A silly harmless game OP plays with his partner isn’t any of that and you making it such is so silly.
I’ll add this too.
OP didn’t say exclusively women. That was vk6flab’s assumption. OP gave a female example, but didn’t say it was only women.
Also, who said being a slut was a bad thing? A woman who embraces her sexuality and has fun at a wedding looking for a sexual encounter . . . is an empowered woman.
Yeah my definition of a slut is not necessarily a bad thing. For me it is a confident woman who views or treats sex as a man does.
