I would definitely advise explaining the difficulty to your boyfriend - it will be good to have it out in the open.

I would experiment with the suppositories in non-critical situations, eg when you're at home and don't have to go out for a while. Glycerol suppositories (which I was recommended to use by my GP) may be the ones to try first, they may be milder.

For more on my experience see the "to coffee or not to coffee?" post.

Best of luck!
