1. The simple answer is as soon as you feel ready, for me that was about
3 weeks after surgery
2. I made sure it was empty and taped it down so it didn't flap about
when things got vigorous
3. My new improved health sent my libido off the scale so sex improved dramatically both in quality and quantity
4. I found the stoma made missionary position a little awkward so we just experimented with other pages of the kama sutra instead
The key thing is confidence, if you are unsure and uncomfortable about
your stoma this will affect your sex life. A caring, loving partner here is an absolute godsend once I realized the bag did not bother her I became much more confident and whay-haaaay!
