Hi, Recently My Girlfriend And I Have Been Having Sex

Hi,
Recently my girlfriend and I have been having sex more often and probably Asa result I have been masturbating less. Today, when I used the bathroom, it felt like something was left over in my penis, when I squeezed it a small semen like substance came out, it was clear with stringy, sticky white substance in it. Now tonight my lower abdomen feels tingly. Should I be worried?
