Relationship Advice

I am in love with my boyfriend, we have been dating for 3 months. We never had sex, because he knows that I am not ready and he respects me for that. He is a great guy. Anyways I think it’s time to show him that he means a lot to me. So Here’s my idea on valentine’s day: go to a very nice romantic and nice dinner, go to his office, give him a massage, play the “drinking game” with him and then have sex that night.
What have your girlfriend done to you that was nice?
Ladies what were some romantic things that you did to your man?
Also I can spend $500 on anything (places or gifts) but we could only spend 6 hours the most together, coz he got work the next time.
stories and ideas are greatly appreciated.
Thanks in Advance
