Hi, You can erect your penis and the only problem is lost it when the penis touch vagina.  The penetration is usually difficult and hard when you insert it during the first few attempts.  You can apply lubricant or topical Xylocaine jelly after penis erection to induce smooth penetration.  Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
