Hi I am 27 Yrs old guy. I am having problem in doing sex with my another girl friend. My penis does not get erected. When I do sex with first girl friend, It does get erected and able to do sex but it's not same with another girl friend. Please advice what I can do to enjoy sex with another girl friend.

Just clarifying you have 2 girlfriends at the same time? If so how much time is between sexual encounters? Sometimes it can be difficult to have sex very often, so that could be a cause. Do your girlfriends know about each other, could guilt be a cause?

Or is this a second girlfriend, and your first one is no longer in the picture? If that's the case, has anything changed between the time that you stopped seeing one and started seeing the other? Is it possible you have an STI? Are you still getting morning erections?

Yes I have 2 girlfriends at the same time. My second girlfriend know about my first one but i did not tell anything to first girlfriend. sometimes it is 1 day of gap in Sexual encounters while sometimes it's 4-5 days gap. But the problem is my penis does not get erected with always this second girlfriend. We try hard so It gets erected and then instantly I got done so I am not able to insert it.

And yes I am getting morning erections. And can you please tell me what is STI?

Your help will be really appreciated. Please suggest what I can do?

Sometimes too frequent of sex makes it difficult to ejaculated- but that wouldn't explain only one. Have you never had this issue with your first girlfriend?

A STI is a STD - Sexually transmitted Infection/Disease. But again, that wouldn't explain why you only have issues with one of the women. Which makes me wonder if it might be psychological. Guilt, anxiety, stress can make it difficult to keep an erection.
