Horny :)

My boyfriend is in the military and just visited me recently. We had sex and it was both of our first times. It was average I’d assume, it didn’t really hurt me like I thought it would. But now he left and is back on base; the next time I see him might be August or maybe December, either way it will be awhile. So now since I know what it is like for him to satisfy me, how can I do that to myself? I’m very horny but it is different when I do stuff myself and when he does it, so how am I supposed to keep myself calm and maybe satisfy myself?
