There are many issues here which have the potential of not working out. But the easier one, first FYI, an erect penis, more than 2 and half inches, is good enough for sexual intercourse - as long as it’s ready enough. I hope you have no other related issues with hormones etc - if than be the case - you have to see a doctor as well. You can also try different sex positions to get better sexual experience - when the time comes, but start reading up. Now comes the 2 inches difference between you - It may be just 2 inches but for many men- this is a HUGE matter and for women too. She may not even go ahead with it - let’s be candid and look for a guy above her height - hard to find tho. OR she may be ok with it. But, will you be? Many men have real self esteem issues linked to taller than them women - they get commented upon, are at the receiving end of jokes ... many of them even about size of penis - will you be able to handle that all and be fair to her? Not an easy decision. PLUS its not all your choice No? She has to agree as well - yes? So take the first step and see how and where it goes - keep all these issues on the table to discuss - when and if things pick up momentum. All the best. https://lovematters.in/en/our-bodies/good-body-image-vital-for-great-sex If you would like to join in on an elaborate discussion on any topic, feel free to join our discussion board, ‘Just Ask’ https://lovematters.in/en/forum
