Why am I have difficulty urinating?

Yes you can tighten up the vaginal muscles. Do this exercise a few times a day and both you and your boyfriend will switch on to feel the difference.
Keep squeezing your vagina as if you be stopping yourself from peeing. Do this for about 5/10 mins. 5/6 times a morning. After a few weeks you will notice and so will your boyfriend how strong you can grip his penis when you are have intercourse.
