My Mistress (trans woman) loved it when I used this on her during and before giving her head. She came so fast and so much. She was throbbing after only a few minutes of using the horn vibe on the tip of her cock. The noises this vibe made her make were so fucking hot. I recommend starting by slowly rubbing in circles until your partner's cock (or your own cock) until it gets super sensitive while stroking your cock, then continue to stroke once it is sensitive while holding it in the most stimulating position where you or your partner are squirming from enjoyment. Then once they are about to cum, pull it away. If they don’t cum immediately, put it back on and repeat until they bust their nut. My Mistress loved this toy, and I will absolutely use it on her every time I suck her cock.
