(NSFW) How do I tell my boyfriend he’s never made me finish before?

Throw away because TMI.
Hi Reddit, I 19F and my boyfriend 19M have been dating for around 3 months. I’m on anti depressants and anyone on anti depressants knows how it can mess up your s3x life. No one has ever made me finish before, ive only been able to get there a few times when I used v!brator on highest setting for 20 mins and trying really hard.

I wasn’t planning on lying to my BF about finishing because I hate lying but I was getting so frustrated with myself for not being able to and I also didn’t want to make him feel bad. Don’t get me wrong, everything we do feels GREAT, but I’m just unable to get there.

I don’t know how to tell him I don’t want him to be mad that I’ve been lying and I don’t want him to feel bad cause it’s not really his fault.

I’m sure a lot of women on here have experienced the same problem, so how should I tell him?

TL;DR I need to tell my bf he’s never made me finish before but I don’t know how to.
