Dating a guy that’s waaay more experienced

Okay so I’m 18 and I had my first kiss a couple days ago and this guy is amazing he’s 20 and hes been in serious relationships and hes had sex and basically he knows what jes doing and the kiss was really awkward because I had no idea what I was doing and I was lowkey embarrassed but it was fine because we both kinda laughed through it but like I realized I genuinely didn’t know what I was doing. SOS.
