hook up dillema

im 17 and i was hooking up with this guy last night and this was my first time ever reaching 3rd base so I had never given a hand or a blow job. Everything about it was great but when i was going down on him, i didn’t know i needed to spit in my hand first so i was literally giving him a dry hand job and i didn’t realize it was bad and he didn’t want to make me feel bad so he was like ended it quick let but im just realizing it now and i feel rlly bad. What should i text or snap him to apologize and assure him that it will be better next time, cause i dont want to have scared him away cause i rlly like him.
