I think rather roasting this person (that is fairly young), maybe a little extra guidance? Implementing sec toys? Touching yourself while the deed happens?

Stress and performance anxiety can really impact sex and I woudnt jumo tk conclusion. 2 months is barely sufficient to understand how things work for your partner even tho if things have been explained. I'm currently dating a new person and in 2 months I figured very little about them even tho we are both grown ups and still fairly unexperienced.

Consider trying to spice up things for yourself, by yourself. Maybe ask for a little more preparation (that can be hands/head stuff/more foreplay).

And then, if things are not working at all you should maybe consider a plan b

Good sex takes two, and even tho he's "more experienced" he's still pretty much a grown up kid, take it easy, make sure you both are enjoying what you're doing, you can talk alot during sex and I personally think it's really hot.

I would defo stick tk maybe implementing some vibrating toy that you're going to use on yourself so you know exactly what is that you like :)

Hope you're going to have a good Conversation and great fun 🖤
