Why can't I get an erection with my girlfriend?
I love my girlfriend so much. I get an erection even just thinking about her or seeing her.  But the two times we tried to have sex I couldn't get an erection.  We've only had sex once and it was a long time ago. 

Why this is happening and what can I do about it?

<p>I'm sorry to hear of your problem.</p><p>First step as always when a possible medical explanation exists, go for a urology check up to either your internist or a urologist.</p><p>Once you know there is no medical reason which would prevent an erection, then we can consider the psychological and emotion based factors.</p><p>Maybe you're nervous about your sexual performance or that your gf may be disappointed in your performance.</p><p>Men often mistake their own fears of performance failure with the assumption that their partner thinks about sex as a performance.</p><p>Talk with your gf about whatever is on your mind which may inhibit you from enjoying sex.</p><p>The reasons are endless.</p><p>What matters is to have a heartfelt dialogue with each other.</p><p>The emotional support which comes through such an intimate conversation may very well be the catalyst for a more relaxed and satisfying approach to sex w your gf.</p>
