PE - Inexperience or actual issue

Starting a relationship after not being in one before, so everything is new to me. When we are together, it’s usually just cuddling and kissing, but not long after we go any further, PE happens and I have to pull away out of embarrassment. I don’t know if she knows about it yet. I’m just wondering if it’s from inexperience or if it’s an actual issue that needs to be solved?

Try not to stress or be down on yourself - new / first relationships are exciting and things can run away on you - try to take it slow and be aware of your body and slow things down as you need - ask to go slowly. Give it some time to see how you go on.
