Frequency of intimacy

I have been with my boyfriend about 3 months and we were both virgins. We have limited chance to get intimate as we both live with parents. He is unable to stop over at mine as I have a single bed. I have stopped over at his twice. Unfortunately both times it was my time of the month. We went away for a mini break and had chance to get intimate so we took this opportunity. I feel he is starting to get frustrated as we don’t have the chance to get intimate. What can I do to sort this out before it becomes an issue? Any help would be gratefully received.
