I would also add..
- Constantly add new locations
- Keep her thinking about sex by talking about it, or touching her (don't be an inappropriate douche!)
- Try new positions
- Toys
- Cannibis
- length should be varied (I do about a 1:1:5 quickie to 30 mins to marathon ratio)
- ejaculate up your spine (google it)
- Food
- Restrain her
Long story short... If a woman completely trusts you, you should be able to do ANYTHING to her. The one exception is anal, cause some women are just not into it, no if, ands, or butts...
And I want to reiterate what
@marmel75 said... many many (if not most) guys fail here. It takes a conscious effort to go full steam ahead every single time...
You should fvck every time like it's your first time and pretending it's your last time all rolled into one. Passion, aggression, no holds barred
