Most guys are totally grossed out to find blood on their weewee after sex, so this site offers an interesting solution...
The INSTEAD® Softcup® is made entirely of hypoallergenic, non-toxic, non-irritating, non-absorbent materials that have been used for more than 20 years in the health care profession. Cleared by the FDA, it has undergone extensive laboratory and human clinical testing. And, the INSTEAD® Softcup® has NO LATEX, which is good news for all women out there with latex sensitivities!
It holds at least twice as much menstrual fluid as a tampon, allowing some women to go at least twice as long between changes on heavy flow days. On a light day, most women find they can wear one INSTEAD® Softcup® the entire day without changing or risk of leakage. Athletes rave about how the INSTEAD® Softcup® carries them through a long marathon or triathlon. Travelers don't leave home without it!
Wearing INSTEAD® Softcup® during your period, you and your partner can enjoy "clean sex"and he won't even feel it's there! (Note: the INSTEAD® Softcup® is NOT a contraceptive!)
Because INSTEAD® Softcup® holds menstrual fluid entirely internally, it can help eliminate dampness and reduce odor caused when even small amounts of menstrual fluid leak and are exposed to air, which even tampons can't avoid.
