Try a vibrator. Or your own hand . Be persistent. When i first started squirting i could only do it with my husband after several Os, but after a while could do it myself on the first O. It just took practice.
Sometimes now, I do it before actually cumming. The theory is this ejaculate's use is to wash sperm away, thereby making the next person you mate with have more chance for his sperm!
Love withers under constraint; its very essence is liberty. It is compatible neither with envy, jealousy or fear. It is there most pure, perfect and unlimited when its votaries live in confidence, equality and unreserve.
~Percy Byshe Shelley
