Small penis

So I’m dating this guy and I really like him. Tonight I gave him a handjob. We didn’t do anything else because I’m on my period and we’re waiting to get tested together before having intercourse. Anyway, I noticed he had a “mushroom penis”. It’s when the head is big and the penis shaft itself is skinny. It’s the first time I’ve seen that. It was pretty small also, length wise. But I know that what matters most is how you work it, so I wanted to ask does anyone on here have a boyfriend with a small penis who knows how to fuck? I’m worried that it won’t do much for me and I won’t enjoy it.

- I didn’t think I would even have to mention this but I did not & will not make him feel bad for it. I have just never seen this before and my ex was huge, long and thick, so it was just different.
