For those that can...

So I discovered that when I masturbate with a vibrator I squirt almost every time. I told my boyfriend this and he’s excited to see this happen, but I’m just not sure having sex with him is going to make me squirt the same way when I use a vibrator. For those that can squirt, can you only when you do things to yourself or is your partner able to get you there? And if anyone has any tips for me to squirt during sex it would be appreciated
