Am I at risk? What should I do?

I am not in any birth control method and I recently finished period. I always use a condom to have sex with my bf but this last time we had sex (yesterday July 16 as marked below) we tried for the first time he putting it inside without a condom for only a second (it was a quick in and out only did it one stroke/time). Before doing that he had a wet transparent fluid on the tip which he cleaned himself with a towel to be dry and he inserted it quick and only once. When he took it out it was dry and no fluid came out, but outside when I touched the tip it got wet and had that watery transparent fluid that got in my hand. He immediately washed his hand and when he touched me just to check how was I he said I was dry inside, but we had a fan close. Then he washed his hands again and so did I to give him a hand job until he had a transparent and white fluid which seemed like cum (white and clear with a watery texture was a lot), but he was still hard and minutes later he finally cum (which was white and clear but with a thicker texture and was less amount). I am now really worried if I’m going to be at risk because I know it was only for a second and one try but I’m scared if I am still at risk and don’t know what to do now. Please be nice while answering?! 😣
