If its your first time don't worry so much about anything. Just
let her know its your first time and just let it naturally happen.
Forget about skills, or techniques or anything because there is no
way in hell you're going to be able to manage all that given that
its your first time.
Just take it slow and really savour it buddy, you're only a
virgin once.
From then on, you can start to take your sex life more
seriously.
Some tips
1) Women need to be warmed up a lot more than men. It often
starts emotionally and mentally. Before you even touch her, its
possible to have her in such a great state that everything just
falls into place naturally later. Tease her, stimulate her, make
her feel, and do this all without touching her. Stimulate her mind.
Send her a few naughty texts, listen to her when she talks etc ...
These things turn her on, even if they might not work so much for
you.
2) Women are often quite sensitive down there, so you need to be
gentle Gentle soft touches that can build up to gradually to more
firm and quicker movements.
3) Use your tongue and not your fingers the first few times.
Simply because you're probably going to be extremely bad with your
fingers, and probably too harsh. The tounge is a lot softer and is
often the best route to go for the inexperienced.
4) Talk dirty. Mental stimulation is a big thing when it comes
to sex. Most men just focus on the physical act, but women need to
be stimulated in more ways than just one.
Goodluck,
