There are two dimensions in what you are asking for a boost: PE and your relationship to your girl.
Now if they are interwoven, this will get complicated. PE should be for you and for you only! No woman will base a relationship on dick size. Even if it really would be a factor in the beginning, on long-term emotional aspects, confidence, trust and all that stuff is the reason for becoming a keeper.
So the first booster could be: it has nothing to do with your actual size. So go back to work on PE, no excuse tolerated!
Now what concerns the relationship I’m a strange guy: my only advice is to talk. It worked for me, and I’m pretty convinced that most couples don’t talk enough. About what really happened. About the feelings involved. About how sex feels right now. And if that feeling is only on your side or if it’s mutual.
Talking is risky, sometimes you might discover the truth.
But I still recommend it.
