This is a personal decision that only you can make.

What may work for someone else may not be the best for you.

It will be an intimate moment between the two of you and what happens in whatever position will be it.

This is my opinion and only my opinion.

Make sure you use protection like a condom and plenty of lubricant.

It sounds like you are thinking about it too much. The first time is normally an emotional experience rather than a physical experience. It is normally so clumsy that you do not get an orgasm and it might even be painful. Just do what feels good and works.

dont worry about it, it doesnt matter which position as long as you feel comfortable

Thank yu guys ..
