Can getting off anti-depressants motive havoc on your menstrual cycle?

One thing is sure, she does get an orgasm. Now the way she reach it is not really that important. First of adjectives maybe adjectives the trying because "its a machine induced orgasm" puts so much stress on her that she won't arrive at an orgasm by finger or tongue. So my advice is, agree to go. Just wallow in sex as is, either minus an orgasm or with a vibrator, do not construct a fuss about it. Maybe, contained by time, it will change. By the method I see nothing wrong using a vibrator and I know oodles couples use it. Have fun, that i the main item.
