The taste and smell of semen varies a lot from guy to guy. What he eats can have a direct effect.
It could be something more though, like urethritus (sp?)
or another tyoe of infection.
Are u seeing a fertility DR.? Don't have fears about not getting pregnant right away (took me and my wife 5 yrs of trying and treatment for our first, but we both had physical problems to deaal with.
Our Dr. said if you took 100 FERTILE women and men, it would take at LEAST 1 yr to impregnate them all.
One of the 1st things the Dr. will do is have your man give a semen sample to be checked. That will reveal any and all problems if any exist.
