So I [M23] am in a relationship with a girl [F25] we’ve been together just about 2 years. As of right we both love eating each others asses and tongue fucking each others buttholes. It feels so good. When it comes to her, we’re able to do lots of butt stuff like anal sex, butt plugs, licking and eating. With me I am always scared of not being clean and there has been a couple times where it’s gotten messy. Well I want to let her do more stuff to me, so far she’s put a finger in me, and we tried a buttplug but it really hurt! I just bought some anal beads that I think will work good and she wants to buy me a prostate massager. I’m gonna use some poppers and a lot of lube. But I really want it to be nice and clean for her. What can I do to make us both comfortable and mess free?
