Yes. It doesn't matter if it is soft or hard. A penis can release semen as pre-cum or ejaculate even if it is soft. All that matters is whether there was viable semen that came in contact with your vagina. Though there is only a very, very, small possibility, there is still a possibility. If the penis was wet in any way from liquids originating from it, such as pre-ejaculation, then you have the possibility of being pregnant.

A dry toothbrush is already frozen, that is, solid. It becomes solid well above 100 Celsius, the boiling point of water. If the toothbrush gets too cold, near -40C, it may become "brittle" and snap. Of course if you store the toothbrush "wet" the water on the bristles will freeze near 0C, but will melt quickly under water.

You could try a warm wet wash cloth; or even a very soft toothbrush with a small amount of toothpaste on it.
Do you mean like wet with water? Yes, you could get a girl pregnant even if you are having sex in a swimming pool. Do you men wet with pre-ejaculate? Pre-ejaculate contains sperm, so it can make a girl pregnant, even it you didn't ejaculate yet.
