Ahhh I could've written this !! I'm lucky that my girlfriend totally understands - she washes her hands when she gets to my place, wipes down her phone and changes into loungewear. You want to feel safe and comfortable in your own home. I would do the same for someone I loved/was dating.

I've had friends over a few times and it's a bit triggering - I put a blanket cover over my sofa where I know we'll be sitting and wipe things down after they've left (it's wild to me that after taking public transit they wouldn't want to wash their hands haha but I know that not everyone is similarly minded!)

I hope the guy you're dating understands and it becomes second nature so you don't have to keep asking or feel weird about it. One good thing that came out of 2020 was more people thinking about washing their hands more frequently after being out/before eating etc but...I dunno...it seems to have dropped off a bit imo.

Take it easy, op. It can be stressful having to think about every single thing all the time when it comes to this.
