Sex problems 😬

Me and my boyfriend have been dating for almost 2-1/2 years and we’ve had sex uncountable amounts of times and some have been amazing and some n out so , but I’ve never squirted like I orgasm and my body goes really speak and twitches but never actually squirted , I think it let’s my boyfriend down cause he thinks he’s not doing a good job and Idk what to say to him cause I don’t know why I don’t squirt

Any ideas 😬
