Me and my 46 year old fiancee has sex on the regular. I have noticed that when we sex and he ejaculates, there is very little to no semen. He does have an ejaculation, but as I say, Its not like the normal ejaculations  am used to seeing. Could there be a problem?
Hello, SEMEN Color, QUANTITY AND THICKNESS changes according to physical condition and sexual intercourse / masturbation timing and related mental and physical conditions.  Therefore, don't think too much about the thickness or quantity of sperm. If you want to know the quality of sperm, get your sperm checked for that. For Healthy Sperm, Eat More Vitamins.(Deficiencies in vitamin I have been linked to sluggish sperm and lowered fertility) Minerals.(Inadequate levels of zinc can cause lowered sperm counts), Fatty acids, Folic acid, Lycopene, and Chat Doctor.  Include sprouts in your daily diet to improve sperm count and quality. Hope I have answered your query. Let me know if I can assist you further. Take care
