It is important that you don’t just bother digging in.  It is important that you participate in seductive foreplay before actually digging in with all your energy.  Kissing, touching and mixed breathing are all essentials which you have to follow to prepare your own body for a quick blood circulation to erect firmly.  If you are just going to blindly dig in, then your body is rushed in to the result and you might not produce a proper result.

Mind racing and thinking too much of the climax can also have you come time ahead.  These are all things that you might not want to happen.  So, practice a bit of breathing and some meditative techniques to feel relaxed.  You need to approach the whole of the sexual mechanism slowly and one by one.  When your senses are aroused, then you will speed up automatically. This is very important in a way to not have your partner feel like a rape victim.

Rather than getting worried about your cum, you better do some research on a proper foreplay, and how to have yourselves controlled while you are inducing her in the foreplay. Most women tend to get completely aroused during foreplay and when you plumb in following this then both of you might achieve orgasm more or less at the same time.  For enhanced, firm and right erection you can try a pill of Sildenafil Citrate. If you are reluctant to ask for it in the drug store you can order it confidentially in the online pharmacy.
