Sperm count low

About three months ago our doctor ordered a sperm analysis, he said we could do it whenever we like. We have been 7 months TTC. So we have been holding off. In past relationships I remember sperm being thick and white. My fiance is white, sticky, and watery. Not thick at all. Could this be a sign of low sperm count? I've brought up the test but he just puts it on the side. I'm sure he is nervous to do it, cause who wouldn't be? I know its takes a healthy couple sometimes more then a year to TTC. Just want some input. Thanks!! ❤❤
