My experience using PRESEED

So my husband and I have used preseed twice so far during my fertile window and he said he feels a huge difference when during ejaculation. (Be aware that I do not have vaginal dryness, I am pretty well naturally wet down there but decided to use preseed because we have been trying for about 6 years and I have heard lots of success stories.) The difference he feels is that when he ejaculates it feels like the sperm actually gets loose and feels free like it's able to swim into my cervix whereas before, he always felt a blockage when he previously would ejaculate inside me like something was blocking his sperm from entering my cervix before preseed. Anyone else experienced this or partner felt this same way?????
