love & sex

So Ive been with my bf for 3 years and he's the only guy I've ever been with. I feel bad but I don't think it's him it's me because I don't even know if I'm getting an orgasm or not. I don't know what an orgasm actually feels like. I lost my virginity with him and only have had sex with him. What does it feel like? How will I know if I've had an orgasm or having an orgasm😭 HELP!! I enjoy the sex we make some amazing love but this whole thing about not knowing what an orgasm is killing the mood sometimes like he'll say to come for him but I'm just there like wth 🙄🙄 help help please I want to enjoy our love and him actually get what he wants 😔 I love to satisfy him and I actually want to feel the connection with an actual orgasm.
