Oral sex can make a great foreplay activity or it can be a great sex act all on its own, and not just a prelude to sexual intercourse. Not all women can have an orgasm from vaginal stimulation alone—in fact, the vast majority can’t. Surveys have shown that something like three quarters of women require clitoral stimulation to have an orgasm. There are other reasons that some women may prefer oral sex as well; some women find intercourse painful (this is more common than you might think). Oral sex is also a great way to have safe sex without worrying about birth control. Practical reasons aside, it offers you yet another way to connect to your partner and have a good time.
For some partners, oral sex is a form of foreplay, while for others it may be the main activity. If it’s going to be the main activity for you and your partner, you might want to do some additional foreplay first to warm up for the main act. If oral sex is your foreplay, it can really give your sex life a boost if you have timing problems during intercourse. Premature ejaculators can sometimes solve their problem just by getting their timing to match with their partner’s this way. Women typically need significantly more time than men to get aroused to the point where they can climax, so licking pussy can help your partner get to the point of arousal where she can climax at the same time as you during intercourse.
