totally agree with this.
Having Nuvaring & TT is reliable, but again, it's only 99.9%. There is always that 0.1% chance. If MM is not willing to take that chance, then you should refrain from intercourse during the "dangerous" days, or refrain from it altogether. There are always other ways to satisfy the desire..
