What should I try?

So I've been dating a guy for about two months I've known him for two years, he was my best friend in high school. So for his 18th birthday I thought I'd give him the perfect gift (sex). So we started making out on his bed and then he started taking my clothes off so I started taking his off.. Turns out he has a smaller then average penis 👀 But I kept going cause I really like him, i faked an orgasm cause I felt like he was starting to lose confidence and he even lost his erection for a minute and then I gave him head lol. But if you've had experience with a smaller penis I would love some tips. I really like this guy but our sex isn't that great.
