Delayed Gratification?

Hannah
So recently the guy I have been seeing not super seriously and I have decided to be more serious and commuted to a real relationship. There is an age difference and that's originally what put a hold on a real relationship between us. But now he and I are both ready to be with each other. However there was a small thing we both agreed on, we cannot have sex again until August... I understand that it will help us grow on more levels than just sexually, but to stop what we've been doing almost weekly since October is extremely hard. 
Is there things we could do for each other without breaking our promise but not give us major frustration until August?
