I cant get wet

Sex with my man has always been good, because he is loaded and he knows exactly where to go and all. He turns me on like every single time... even the thought of him gets me wet down there. ... so here’s the thing eeeh., for two times now he has struggled to get me wet. And for this two times I was a little bit mad or moody... any logical explanation for this... I just need support because am feeling all sorts of things
