Well this is awkward but easier than asking my friends.

Sex isn't a regular for me lately as my partner is pregnant and almosst due.
I haven't slept with anyone so I'm positive I do not have an sexually transmitted disease,

However I've been having trouble with my little swimmers a few months after my partner fell pregnant.

It started with my sperm being a bit low when I came, and after that I could feel it burn inside for a little bit.

This lasted a few weeks, however now there is a lot more swimmers and the cannon has more gun powder, and the burn has left but the sperm is now yellowish brown.

Can someone please help?
