orgasms

So, i have been with my current boyfriend for about 2 years now. We have very regular sex, at least once a week (but usually more). I really enjoy having sex and it always feel really good! But i’m not sure if I have ever had an orgasm? I always feel super good while having sex, and usually feel kinda tingly afterwards, but i’ve never had like a “climax” moment? I’ve never felt like there was a point that I could pin-point that felt better than the rest of the sex. Sometimes, I just make it seem like it when I feel like we’ve been fucking too long, or if I just can’t handle how good it feels anymore.

My boyfriend always asks if I “came”, and I always lie about “if I do” or “how many times”.

How do I know if I’ve orgasmed or not? Is this normal? HELP
