First blow job !!

I had a really funny experience today giving my boyfriend a blow job. I've never given one and god I felt so scared. I was like what if his dick stinks, or tastes bad or just basically knowing id put a dick in my mouth. Well he wanted me to give him one so I was like okay but I was very scared and no way confident. I told him to cover his face with my pillows so that he won't see me and he did. I licked it at first to see if it would taste bad😭 and then I put it in my mouth and sucked it twice. Only lasting 5 seconds. I peep him taking off the pillows and caught me with his dick in my mouth. So embarrassing 😂😂 anywho it didn't taste bad and instead felt so squishy like if I had marshmallows in my mouth😂 maybe I'll do it again butthos was so embarrassing and scary 😂😂 any tips on how to get good at it ?
