In need of help.

I don’t how to start this conversation off really. ☹️

Basically for years I’ve had a “problem” but when me and my boyfriend have sex and I get to that point of finishing for some reason or another I can’t. It’s like I get scared or something. Does anyone have an idea why? I know you might not be doctor or sex therapist but it’s starting to bug me a little bit now because I have to pretend I have so I don’t make my boyfriend feel bad. Also because of this I get really bored of having sex . I’ve/ we’ve used sex toys but I get the exact same feeling. 😩

Any suggestions will be great! Thank you for taking your time to read this especially if you give me any tips. X
