I have been having a problem with this girl i recently have been hooking up with. Iv had sex numerous times with no problems at all and now with this girl i get a full hard during everything (4 play etc) than as soon as were about to do it it goes to a half boner half limp stage i dont get why its putting alot of stress on me and all i can think about is what shes prbly thinking about like look he cant even get hard etc. Its happend to me 2x with this girl and i really want to do it im horny and all but it just goes into this stage thats like torture to me being half limp half hard. I never have problems holding erections when we do 4 play when i masturbate etc any sugestions?
