Do we all squirt? and the IUD. TMI

I have noticed that my boyfriend always tries to make me squirt, but it’s impossible for me. Even if I drink 3 lt of water a few hours ago I just can’t pee. I guess I’m just too good at holding it? I decided to look online and even watched porn videos and I did manage to find my “g spot” and felt very close to squirting yet I did not. I only orgasmed. After this though I felt like I got weird cramps and pressure on my cervix and I got the iud 3 weeks ago so I went to my dr and told him and she said it’s in place and the strings were there. She said maybe because I’m ovulating my cervix was different (she even inserted 3 speculums because she couldn’t see clearly inside of my vagina). After that the cramps magically went away and I didn’t feel any discomfort. I’m a little scared to try again and move my IUD but has anyone been in this situation before? Where they want to squirt and you can but after a while you are able to? My boyfriend has told me not to force myself if I can’t or feel uncomfortable but I feel like it’ll feel good.

Thank you
