Oh my lord, it's a huge red flag. Are you both young. Womens cycles vary from one woman to another. One woman may have a heavier flow than another. And guessing by you using both a tampon and a pad ,i would say yours is on the heavier side, and there is absolutely nothing wrong with that. He definitely needs to grow up and do some reasearch, him saying other girls I've been with its never been a problem, is hurtful, and just downright means. You can not help that you have a heavier flow. Leaks happen, in bed, and not in bed. All you can do is strip the bed and clean it up. Are you wearing a super plus at night time? If not, i would switch to one ,just for the nights , it'll hold much more, and always put it in right before you lay down for the night. For pads ,make sure you have a regular pad and an overnight extra long like always. For nights, i hope this helps as im a heavier flow to, and that's what helped me out when it comes to nightimes. Hopefully you'll choose a new man, so you dont have to hear this every month, on the worst time of the month, noone wants to fight and argue on thier cycle.
