Hi Mike, welcome from another APR Newbie.
Yes.
It probably was pre-cum, which is thinner, clearer, and more watery than the more thicker ejaculate which carries the semen. Is this what you experienced? This happens quite often when I edge and I wouldn’t worry about it.
Mike, why don’t your complete your PE Statistics so you can keep a record of your gains? See “quick links” above.
Good Luck and Good PEing.
