Hello Fapstronauts, Help me answer a few questions about erection. I am 35 and on 90 days challenge. 45 days completed. 1) Is it realistic expectation to "think" about sex moments with a real lady and achieve a rock hard erection even with thinking about it and maintain it till the thought process. 2) Is it realistic expectation that when you are alone and aroused at your work place chatting to your distant girl friend about last sexual encounter with her and stay rock hard throughout the "sexting"? 3) At the age of 35, is it a realistic expectation to have an good erection anytime you think about sex and maintain it? the above used to hold true in early 20s.
