You only live once bud. I guarantee that not sacking up and telling her will be way more regretfull than doing it. Plus, the high from stepping off that cliff of the unknown is incredible. Do yourself a favor and make yourself happy, tell her!!! :2thumbsup:
If you are smoking weed together, you really should be able to muster up the courage. Maybe you need better weed =P I like the hand suggestion, just don't be 100% sure she'll get the hint. I've been in her hypothetical condition and had no clue really do to some insecurity =P
be like " hey baby girl, I noticed you checkin me out for awhile now, and I must admit Ive been guilty of doin the same thing a time or two.. Now, Im not sure what I want, (gently stroke under her chin and side of neck) but I just have to express the way I feel to you now, and see what happens." (kiss)(fuck)
Please don't tell her, she will respect you more if you show her with the way you act and your body language. Keep some playful mystery in the beginning.
