Can’t orgasm during sex+clit stimulation!!

Hi!

So the thing is that I can orgasm through oral or masturbation, and I tried to stimulate my clit while having penetration to have an orgasm, but I can’t focus on having pleasure or simply I don’t feel anything. It is so frustrating bc I want to orgasm while having sex with my bf but it feels imposible😭

The same happens if he is giving me oral and he sticks a finger or two inside.

There is someone that feels the same? Or maybe can I have some tips to improve that? I want to find my g spot too to have more pleasure bc most of the times the penetration doesn’t feel that good like other people claim it to be ☹️
