It's the way they cut the scene and Howell's acting that added the sexual connotations: Foyet removed his shirt, showed Hotch his torso and purred "do you like my scars?" before straddling Hotch and positing about impotence. That combined with "the blade goes in so much easier if you relax," and yeah, there was more than "this isn't sexual, remember that next time" going on there. Whether it was thrusting into a wound (a surprisingly common sadistic fantasy) or just pressing his erection against Hotch, either way, there was definite sexual element to what he did. Even if Howell was just "faking gay" to freak Hotch out.
