My girlfriend and I have just discovered anal sex and enjoy it a lot; I really enjoy having my cock in her tight asshole. But there’s one thing I want to ask about: the next day after anal sex, I have a painful backache. We do the ‘spoon’ position, and while it is happening, I don’t have any pain at all. Do you know anyone else with this problem and do you have any advice for me?
–Want to Get Laid, Not Laid Up
Welcome to the wonderful world of anal sex! It sounds like you would be off to a pleasurable start except for the painful aftermath. My first impression is that this is probably muscular pain. When you start a new sexual activity, you use a bunch of muscles you’re not used to exercising on a regular basis; just like if you started a new work out regime at the gym, your body needs some to adjust. It may simply be a matter of awakening those muscles and getting them back in shape.
It could also be the position you’re in is putting strain on your lower back. The next time you do it, try to concentrate on your body movements and see if the position is uncomfortable for you; perhaps you only need to make a slight angle adjustment and it will feel better. You can also do regular stretching and simple exercises to avoid muscle strains. Find a personal trainer, physical therapist, or someone knowledgeable about working out and ask them to recommend some exercises for strengthening your lower back. Once you get your back in better shape, there will be no stopping you.
