Hey Kristi! There have been a few discussion on this forum about sex - I've looked for them because I had the same concerns! From what I've read, sex is just a no-go for most folks. It often hurts, for both men and women.
There was no way I could have had sex with my hubby while I had my fissure! I was in too much pain. I was quite depressed about that. I was also not able to do a very good job making him happy in the various creative ways that are available. The positions required for oral sex were just too uncomfortable, and I didn't have the energy to pleasure him by hand. I was just too worn out to do all that work!

(sorry if I'm offending people, but I tend to talk about sex pretty openly). Chronic pain and anxiety also tend to kill the ole libido!
Now that I'm healing and feeling better, I intend to make up for lost time! The lack of sex definitely compounded the depression I suffered. My hubby is amazing, though, and he was happy to cuddle and he gave me nice long foot rubs and shoulder rubs. I owe him so much, I'm going to be very busy doing some rubbing for him very soon!

The impact my fissure had on my sex life was a pretty major motivating factor in my descision to get the LIS and get myself healed. Don't despair - you will feel like having sex again and it will be enjoyable again too!
