Just communicate w your boyfriend about your needs. It's probably be an uncomfortable conversation, but if this is seriously something that you want, it is better to be above board and talk with him. Assuming you're all emotionally mature and are able to communicate, no one should get hurt.
Communicating one's needs. They both understand as a long-distance couple that there is a lack of physical intimacy between them and that can be an issue for many people. Just communicate that there is a need not being fulfilled and then discuss what solution would be best for the two of them. It could be opening the relationship or visiting if that is feasible. It is just necessary for a healthy and stable relationship.
