Wait has no one discovered what I do?? Just stick the penis between your legs (answering from a woman’s perspective) so it rubs against everything. Feels fantastic for both parties, and especially good for women who don’t orgasm from sex because you can directly stimulate your clit with the penis. Also orgasm can easily be simultaneous. Yes, it makes a mess, but it’s a male mess that doesn’t stain. I’ve heard this called “interfemoral intercourse” if you’d like to look it up. I’m actually looking forward to my period next week so we can do lots of this.
Oh right, this only works if blood flow is blocked. I use a menstrual cup so everything is contained. I suppose tampons would work too as long as the string doesn’t get caught and yanked.
