Pre-ejaculate (pre-cum) does have a small amount of sperm in it, so it is possible, but the amount in it is relatively small, so the risk of pregnancy is minimal. The greater risk is in sexually transmitted disease.
When you touch your clitoris, the pleasurable sensation is due to the high concentration of nerve endings in that area, which can lead to feelings of arousal and pleasure. This stimulation can trigger the release of endorphins and other hormones, enhancing the experience. It's a natural part of human sexuality and can contribute to sexual enjoyment and intimacy.
It would be much better for your body to use a simple A&D Ointment, like used on babies' bottoms. It will provide a barrier over the area while helping any abrasions to heal. Make sure to gently wash and rinse the area first. You should also have a stern talking-to with your sexual partner-- women do not have to be hurt to have good sex. The clitoris is extremely sensitive and can be injured.
