Sexy Time...

Okay so masturbate a lot and my fiancé and I have sex a lot. I get off every time.

But lately it’s been different. When Im about to get off when masturbating, my legs shake a lot and my clit is eeexra sensitive but it’s like my arm try’s to jerk away or something idk I have to force myself to keep going even though I really really want to. Does that even make sense? It’s like my arm tries to stop and I won’t let it. I’ve noticed these things when my fiancé gives me oral but I obviously still finish because he doesn’t stop like I do. I can still finish but I feel like I have more and I can’t touch my clit anymore because it’s so sensitive at this point.

Does this make sense to anyone? I’m so confused.
