Saturday night I lost my virginity to my girlfriend (also a virgin) and since then I have had a lot of soreness in the penis. I had masturbated earlier in the day not knowing I would lose my virginity that night, and then after we finished she wanted to do it all over again

Three orgasms in 12 hours (not to mention I probably masturbated the day before).
I am leaving to go out of town with her on Wednesday for our anniversary vacation. I would like to be in my full sexual prime my wednesday night if possible. Is there anything I can do to alleviate the soreness faster, and have my full sex drive / erection capabilities back in time?
I am taking fish oil pills to improve the circulation, and I will refrain from masturbation. Would a hot water pack help? Any secrets?
