Because it's not his fault. All my life I've had trouble having an orgasm when being intimate with my partners regardless of how good they were in bed. I've always been faking it and just assumed there was something wrong with me so I never told anyone. Turns out that I can't orgasm because of the very specific way I masturbate which I developed from an early age. So, unless I'm doing exactly that, I just simply cannot reach my peak. I don't find helping yourself during sex anything particularly bad but I can't do that in the way I'm used because it would be weird. Fortunately, thank God, there is a way to fix that, albeit though a lot of work with a sex therapist, but I would love to do that sometime. The reason I want to tell my boyfriend about all of this is because I'm honestly just so tired of faking it every time we do it. I'm still enjoying sex a LOT and not having an orgasm is not a huge issue in itself at all for me. We've been together for 4 months and I would love to be serious about us so I want him to know me better. The one thing I'm afraid of is that he might take it personally and harbor negative feelings for me for faking it even if he accepts my explanation. He's always been understanding but I cannot predict his reaction at all when it comes to this. Any advice? Thank you.
