Why are you asking for people's opinions? This your decision to make. Look, if you wanna get laid, talk to your lady and tell her that, if you don't tell her no. It's pretty damn simple. When my girlfriend and I were talking about sex I didn't go and ask my friends, hey should I go for it? I decided on my own. Godamn, as i said:
If you want to, go for it! If not say no. It's your choice, and it's pretty simple.
Also, what the hell is this? Do you need to plan 2 months in advance to book your lady? 😛
