need some blowjob tips

my bf is coming back after not seeing him since october

i want to give him the best blowjob he’s ever experienced...i usually just do the basics like the up & down motion and swirling my tongue around the tip so i definitely need more tips. i can hardly deep throat lmao so also some tips on how to make that easier

what do guys typically love? what drives you crazy? what do you consider an amazing blowjob?
