I’m small myself, but I can assure you with commitment and determination, you can achieve some success. There has been documented success here, and you can feed off that, start with the newbie routine and take it from there.
I will mention that not everyone benefits the same with PE, so you will have to be patient. There are also other options out there (i.e. surgery) but you should REALLY try a good solid few years of PE before giving any extreme methods a try.
Lastly, I’m happy to hear that you say you would be content with just an inch or two, and I think with a good head on your shoulders like that, you will have no problem earning it. I’m similar to you in length and was able to gain 0.5” in EL in a month of decent PE work. Some gain faster than others, so be patient, work hard, and remember that women are nowhere near as penis-obsessed as us men are.
