wonder if you can help

Hello!  I think my first port of call would be your GP or consultant for a frank discussion about whether this is to do with medication (ie, a side effect), and whether there are any other options available that might alleviate that.  It's generally accepted that doctors aren't always very good at raising the issue of sexual function and enjoyment, but it's really important and should be something that they respect and respond to.   Moving on from that - the fact that you've asked the question points to this being is a concern within your relationship, whether it's for one or both of you.  I suppose where I'm going with it is that sex doesn't need to be penetrative for it to be enjoyable , as lots of couples can't or don't choose to have penetrative sex, and it doesn't affect intimacy or enjoyment. it's just that their sex looks different.  Functional sex does change, but if it's causing issues with your intimate life together then I think it might be worth asking for a referral for psychosexual counselling through the consultant or specialist that your husband is under.  This sounds alarming but (hopefully!) isn't - what it could do is help with returning to a sex life that you are both happy with, even if it is different to how it used to be.  That might be the case going forward too - it might  be that erections are a challenge, but it doesn't mean that there can't be any sex.  The other thing of course is that your husband's consultant might also be able to prescribe something to support his erections, which could improve things too?
