Hard to reach orgasm

So I know many women don’t reach orgasm every time. In my case, I can count the times I’ve came during sex. I get all wet and horny during foreplay EVERY SINGLE TIME and almost about to finish but it seems like I lose sensitivity and I know it just won’t happen! I still enjoy every part of it and feels amazing and also... my man gets a lil bit frustrated too because he thinks he’s not doing a good job and wants to please me! But I feel like it’s soooo hard and impossible! Does this happen to you too??
