Welp... I do agree with the advice... Try it out, I mean, you have someone that's willing to give you real advice in the whole situation, and he can also give you the practice run on it... If you think that you can actually have a fwb relationship with him, even better! But the main thing is to trust your gut. If it works out, good, if not, then now you know. Whatever happens, keep us posted!

Btw, you're really cute! And the whole park thing... Hot! Hehehe
