Is this a reasonable request?

I really need some advice here please. My boyfriend and I have decided to emigrate. It will be 6 months before we leave, and there is a lot of things to sort out. This is my problem: I am considering putting a ban on our love life in the meantime, as an unwanted pregnancy would be a nightmare right now. We've always been careful and used the pill AND condoms, but both have been known to fail. We all know the safest is no at all. I really don't need this added pressure (what with trying to sort everything out about moving), but I also know that it would not be fair to deprive my boyfriend of . Its a subject I don't want to have to discuss with him, as I know he would be devastated at having to give up . Sure, we can pleasure each other in various other ways, but its not the same of course. Its likely that this will cause a lot of problems between us, but the question is, do you think its fair to even suggest it? For the men reading this especially, would you agree to this, if it meant that your girlfriend would have one less thing to worry about when she has so many other things on her mind? (i.e. making the preparations for a new life?) If I was to become pregnant, it would mean that all our plans would be put on hold, or may never happen at all. Remember: a pregnancy would affect us both, so it would be his problem as well as mine. Do you think he would see it from my point of view, or am I being unreasonable? (Also, as soon as we were established in our new life abroad, our life could resume as normal.) Please advise!!!
