is sex all that?
i 22m, have heard for years that sex is the best thing out there and dont get me wrong its neat. but when i have sex i feel like im just going through the motions and i worry that its just me. my girlfriend 20f, will literally tear my clothes off and says she loveing having sex with me. when we have sex usually shell cum a handful of times but ill cum maybe once but sometimes after an hour or 2 the peen will just get tired and go soft before i can cum. i love seeing my girlfriend enjoy it, ill eat her out lots cause she loves it and have sex in whatever positions she feels like and i love making her happy and she loves it. but i dont think im enjoying the sensations of sex as much as she does, for me i do it 90% cause i enjoy seeing her enjoy it and 10% cause its neat. somtimes its nicer for me to just jerk it. is there something wrong with me? is it a guy thing? has it just been over hyped? should i take supplements or something? if you guys have any suggestions please let me know, im beginning to get concerned.
