Hi. Thanks for your query and an elucidate history of you being truck driver now have to go outside hence the change in the sexual behavior than when you used to work locally and had longer timing. This is called premature ejaculation. This is usually related to the stress and anxiety that one ejaculates early. This is a natural process and you can have the similar feelings and proper timing if you revisit your previous habits of good foreplay, intra-play tactics. You have to discuss the issue with your wife to get a proper solution, it is possible that her responses too have changed to make you ejaculate early. These small adjustments will help you to overcome the problem. So do not worry, the answer always lies with the spouse and easy to follow. Only if these measures fail, that you have to visit sexologist.
