In the name of Allah the most gracious the most merciful
The answer to your question is as follows:
(1) Due to the sticky vaginal discharge which is not MANI, you have to make wadhu only.
(2) (i) MAZI, it is sexual fluid which is sticky and comes out slowly during sexual arousal, e.g. sexual thoughts, foreplay, etc. This requires wudu and it is impure. One needs to wash the body and cloth stained with mazi. (ii) MANI, When the sexual pleasure fulfilled, a fluid exits in the private parts at the peak of sexual excitement, is called MANI. When Mani comes out, one feels that something has moved from one place to another. And sexual excitement gets reduced after that. This requires ghusl and it is impure too. If absolutely no fluid exits the private parts, ghusl would not be mandatory.
And Allah knows best
