Question:If you masturbate frequently will you still be able to experience orgasm during intercourse, and will masturbating cause you to become loose?
Answer: The majority of women do not experience orgasm during vaginal intercourse, regardless of whether they masturbate. This is because most women require clitoral stimulation if they are to experience orgasm, because their clitoris is often their most sensitive sexual organ, not their vagina. Women who masturbate are more likely to enjoy partner sex because they are more familiar with their body and sexuality. If masturbation were harmful, it wouldn't feel so good.
The body responds to sexual stimulation the same during masturbation and partner sex. To your body, there is not difference between masturbation and partner sex. Your clitoris responds the same regardless of whether it is stimulate by your finger or that of a partner. Only your mind knows the difference, or cares about the nature of the stimulation.
Masturbation does not cause loss of pelvic or vaginal muscle strength. When the majority of women masturbate, they stimulate their clitoris, they do not insert objects into their vagina. Even if they do insert objects into their vagina, it is no different than inserting a penis. There is no mechanism by which masturbation could adversely affect the vagina. If anything, orgasms are beneficial in that they cause the pelvic muscles to contract rhythmically and increase blood flow the area.
Inserting objects vaginally may stretch the pelvic and vaginal muscles, and if they are not strengthened they may not grasp objects that are inserted into the vagina. Vaginal intercourse and vaginal births can also stretch the vaginal and pelvic muscles causing a loss of muscle strength. The "virgin" vagina is often tight because of lack of use, but a woman can be a virgin and have relaxed and flexible pelvic muscles that allow for easy vaginal penetration. If a woman does not engage in intercourse for an extended period her vagina may lose some of it elasticity, returning to its "virginal" state. The condition of a woman's pelvic and vagina muscles does not indicate her level of sexual experience.
If you do not exercise your pelvic muscles they will not be strong, and could be inflexible, leading to discomfort and pain during intercourse. A healthy vagina is both strong and flexible. Kegel exercises teach women how to control and develop their pelvic muscles. In many respects, a "tight" vagina is undesirable, especially when it is necessary to insert objects into the vagina during medical exams, masturbation, and partner sex.
