How can me and my partner stop being silly when we’re not supposed to be

I love my wifeeee but we’re to silly for our own good😭 whenever me or her try and seduce eachother we do something stupid like throwing eachother off the bed or pulling a stupid face and say “I’m scared”, then we laugh, get turned off, and watch a movie or go and get snacks. She thinks it’s just our personality and I agree! But I’d like to remain serious at times and we literally can’t! Does anyone have any tips 🫢
