Yes you can have anal sex and it is great. I will caution on one thing. The cylinders can often cause some difficulty for you and your partner. I have learned with my last implant (a Coloplast) that I have the option of different levels of size. The larger I make it the more the cylinders poke out the head. What I do is inflate so that they are not as exposed and thus I am able to nail it any way I want. For those use to having anal sex are generally use to it and sometimes I go for all the size both in length and girth. I always had a healthy girth and with my first 2 implants I lost most of my girth and some on length. (AMS 700) The first 2 implants went bad from heavy use and the pump was the problem. I like the Coloplast model all because it gives me back my full length and girth. I find using a condom is messy and as we all know who have implants we loose a lot of sensitive in the glands (head). There are 2 things you can try that will make you have more sensitivity in the head. First take some ED meds such as Viagra. I see all the post about Viagra and all its side effects but I have 100mg pills and I break them in half and that I will half again. If your doctor did his job right there is still tissue that will still carry blood all the way to the head. This will enlarge at least for me to almost it's original size. Second, don't inflate to its max amount. This will leave a tiny more space in the shaft and the ED pills will do the rest for you. I still have my own style of erection every morning until I take a piss. Every guy knows that heavy feeling before you have a hardon. Also I take Testosterone which is a huge help all the way around. My signature will give my age and how long I have used implants. I trust this will help some. I only have the highest of praise for the implant. It isn't totally perfect but if you can't keep an erection and do the job it isn't any fun. On the "T" I feel like a teenager and perform the same way in bed. I expect to keep this up till I am 6 feet under or a 100 years old. The only thing better than sex is making love with a guy who has your heart and you have his. How I perform isn't like the porn movies all because sometimes it takes 15 minutes or on some occasions it only takes 5 all because it sneaks up on you and the waves are so great that you just go with the flow. I top and bottom because I like it both ways.
68, single, have had an implant since I was 42. Goals: to help men with ED; help men over come years of failure; to know their bodies; have a richer fuller sex life whether they or straight, Bi or gay. last I traveled this road starting in the late 60's
