It’s not really that hard. Of course, it takes a real man to do so. I mean, there is the technical way. But before anything you should be able to put her in the mood:
Never Ask. I don’t know but some guys just ask. It’s really a turn off. MFcking turn off! It cuts of that moment from even happening. If you know how to touch, there you go. But hey, don’t touch her there directly. Start from the top and work your way down. Geezh like every guy should know the importance of stimulation.

Hold Back A Little. Just because you’re so horny you’re just going for the goal. No! Have a little reservation. Ease up man! Gently and slowly, that’s the way if you want to see that look in her face. Oh yeah! That look, yeah?
Be Clean. Hygiene is necessary. If you have plans, then wash your hands. Trim those fingernails. You don’t want her to have some kind of disease, right? After all she is your girlfriend. Eventually, you are going to do here now and then. Don’t give me that condom excuse. Be responsible for her and the both of you.
